#### Childhood on Inkwell Isles

Him and Cuphead grew up together on a chain of islands in the Atlantic (Ch 136) called the Inkwell Isles, living with their grandfather Elder Kettle. While for the most part their early childhood was fairly normal and happy they did also get into their fair share of mischief. For instance, one time as children they went into the city and snuck into the *Queen Bee's Hotel* in order to steal some of her famous honey. While Mugman distracted the worker bees, Cuphead snuck behind the employee's door and stole as much honey as he could, even filling his head with it. After stealing the honey the Cupbros fled the hotel but one of the cop bees caught them, and the dish brothers ended up stuck in a jail cell as they waited to get picked up. While they returned the majority of the honey they had to explain to the bees that they couldn't return the honey in Cup's head since it was already in his system. Despite this explanation the bees still attempted to get the honey out of his head through various means such as holding him upside down and using a honey dipper on him (Ch 80).

One day when Mugman was ten years old, they went into The Devil's Casino, bet their souls and lost them to The Devil. After losing their souls the two boys had an argument which ended with Cuphead getting upset and leaving Mugs behind at Elder Kettle's house to go begin collecting the soul contracts by himself. At first Mugs was too angry to follow his brother but after talking with Elder Kettle, Mugs promised to help Cuphead and bring him home safely (Ch 41). The two cup brothers then battled and collected multiple contracts on the Isles, powering up as they went with help from the Legendary Chalice.

After collecting the contracts on the Isles, they attempted to defeat The Devil but were beaten. After losing, The Devil took their souls as punishment and kept them in Hell for the next few months (Ch 172). Apparently, once the soulless Cupbros arrived in Hell they went on a rampage through it's second level and killing many Demons before The Devil got them under control. After that The Devil put them into a pit of sorts where he would have the soulless and bloodthirsty Cupbros kill anyone he wished by sending them in to the pit (Ch 177). After spending those few months in Hell, which both Cupbros has since mostly repressed, The Devil approached Cuphead and offered him a deal- he and Mugs would get their souls back so long as they signed a new soul contract with him and fulfilled it's terms. Cuphead agreed and, after negotiating the terms of the contract with The Devil as best he could, the Cupbros souls were returned and they were allowed back on to the Surface (Ch 172).

#### Living with Black Hat

At some point after their defeat the Cupbros went to live with Black Hat in what Cuphead describes as a "forced foster" situation (Ch 85). There, they were taught and trained by Black Hat and his underlings (mainly Dr. Flug). This training, in part, involved fighting various monsters and some Demons in Hell. They were also used as test subjects for some of the doctor's inventions, such as a shrink ray, and experimented on (Ch 127). One such experiment was getting Angel blood added to both of the Cupbros systems, though this ended up producing no changes in them. Following this experiment Cuphead was taken in for the experiment in which they poured some of Black Hat's blood into his head. When Cuphead was rushed to Hell to obtain treatment due to his negative reaction to the blood Mugman had to stay behind at the casino to wait for news on his brother's condition. Once Cuphead returned from Hell, Black Hat stopped all experiment on them following this incident, only giving them regular check ups or anything ordered by The Devil for the rest of their time in his care. It should also be noted that both Cupbros were injected with a dose of Angel blood prior to Cuphead getting Demon blood added to his system but neither of them ever showed any changes following this injection regardless of what was done to prompt a reaction (Inky Extra's Ch 109). During this time Black Hat also examined the Cupbros souls multiple times (Ch 121). They also continued completing jobs, mainly contract collecting, for The Devil during this time (Inky Extras Series Part 2).

When he was 14 years old, him and Cuphead worked at the Day to Forget gambling tournament. There Cuphead won a game that allowed him and Mugman to move out of the casino once Cuphead was a legal adult (Inky Extras Series Part 2). Ultimately, the Cupbros lived with Black Hat for about nine years before leaving (Ch 127).

#### After Leaving Black Hat's Casino

After moving out of Black Hat's casino Cuphead and Mugman traveled the world completing missions for The Devil.

The most notable of these missions is the Cupbros pursuit of Wilson Wiseton. Just over a year before the start of the story the Cupbros were told about Wilson's archeological dig in the Seven Sands Desert. The Devil had heard about the page in Wilson's Journal that had information on the parts and sent the Cupbros to collect it from him. They were also informed that The Devil already had an inside man there named Salazar who was pretending to be a local guide for Wilson's team. The Cupbros headed to the dig site but when the arrived the site was in ruin, the team was dead and both Salazar and Wilson were gone. From there the Cupbros followed Wilson, first by backtracking to previous known location Wilson would go and then to various hideaways located all around the world. The Cupbros were also competing with an unknown third party who were trying to capture or kill Wilson. They would start many fires around the professor, killed people he met in passing and set deadly traps for the Cupbros in order to prevent them from getting to Wilson first (Ch 253). Of course, since Wilson believed that the people after him were trying to kill him with the fires and he wasn't aware that there were two different group following him he didn't trust the Cupbros when they went to question him (Ch 194). This forced the Cupbros to continue chasing him until they eventually caught up to him in Sillyvision.  In total the chase itself took about a year (Ch 253).

### Book One

Cuphead and Mugman spend the first couple of chapters chasing after Wilson Wiseton, eventually chasing the owl into traffic where he is hit and killed by a car. The Dish brothers stay in Sillyvision until their Boss instructs them to track down the B-Bros and eliminate them. The Cupbros then buy tickets for Warnerburg at the Sillyvision train station where Mugman laughs with Cuphead after Cup injures an employee (Ch 11).

After leaving Sillyvision the Cupbros spend the next week in Warnerburg, listening in on police gossip and talking to the local criminal population in order to track down the B-Bros. When the Cupbros can't find the B-Bros themselves they decide to track down their stolen bag in order to use it as bait to draw out the fugitive brothers. They spend the morning before they head to the warehouse where the bag is being held in a local bar, drinking and harassing other customers (Ch 14).

The Cupbros arrive at the warehouse in the midst of the confrontation between the B-Bros group and the thieves. Upon noticing the B-Bros presence the Cupbros talk with them a little bit about how hard it had been to track them down. During this conversation Mugman introduces him and Cup by name to the B-Bros, causing Cup to reprimand him. Following this conversation the Cupbros then shoot at the B-Bros in an attempt to kill them, giving chase after the fleeing group of toons as they attempt to escape (Ch 16). The Cupbros eventually lose track of the B-Bros group in the warehouse and are forced to flee the warehouse due to the police presence there. Before they leave, the Cupbros also steal some of the already stolen goods from the warehouse (Ch 18).

The day after the night in the warehouse Mugs shows the newspaper story about the B-Bros escaping from the police to Cup. After Cuphead digs up more information on the Warners, thanks to their mention in the paper, Mugman accompanies his brother as he heads to the Warner's water tower. At the water tower it is Mug's idea to knock, which is what calls Dot to open the door (Ch 18).

The Cupbros questioning quickly turns into a fight with Dot. After Mugs manages to hit Dot with one of his blasts, Yakko and Wakko come out of the tower as well. Attempts to question the Warner brothers also fall flat and before they know it the Warners have pulled a large cannon on them. Thanks to Cupheads quick thinking and reflexes the Cupbros are able to avoid both the cannon and the shark filled pool the Warner brothers had attempted to have them land in. However, despite Mugman's attempt to warn his brother, Cuphead is soon knocked out and Mugs quickly suffers the same fate. Mugman wakes up in the midst of the Warners attempted interrogation of his brother. Mugman is quickly able to manipulate Wakko in conversation, causing the middle Warner to accidentally reveal that the B-Bros are heading to Toon Town. Shortly after this the Warners leave the Cupbros to go deal with the police at the water tower door, giving Cuphead the chance to free both himself and Mugs. After confirming with Cuphead that the Warners don't know enough to warrant killing them the Cupbros escape from the tower out a back door Mugs spots and continue their pursuit of the B-Bros (Ch 20).

### Book Two

The Cupbros arrive in Toon Town right at the beginning of the first chapter of Book Two and immediately make a bet about how long it'll take them to track down the B-Bros. The brothers then make their way to a local café to meet up with one of the local informants, Mortimer Mouse, to get information about the B-Bros. Mortimer initially doesn't want to talk without something in exchange so Cup offers him a favor in return. Mortimer originally declines the offer of a favor from Cup and instead asks Mugs if he has anything to offer, to which Mugs replies that he doesn't. Quickly realizing that the Cupbros aren't gonna give him a better offer Mortimer finally accepts the favor after clarifying that the favor can be absolutely anything, including murder. Mortimer tells the Cupbros that the B-Bros were last spotted around Yen Sid University so the brothers head there next after Mugs thanks the mouse. At the university the Cupbros accidentally walk through the magic mural there and get a horrible cold feeling from it. Mugs is so shocked by this feeling that he becomes frozen and Cuphead has to pull him out of the light. The Cupbros then head over to the information desk where Cup begins to question Holly about the B-Bros, but he can't get any information out of her. Mugs instead turns the conversation to the mural and asks whether the cold feeling he got means he is a bad person. After being reassured by Holly that it doesn't necessarily mean he is evil the Cupbros leave the university and head to a local cop hangout to listen in on their conversations in the hopes of getting information. This eventually pays off when they hear a group of cops talking about Dr. Oddswell, whose address they get from Mortimer after piecing together that he's who the B-Bros were here to see. After finding evidence that the B-Bros broke into the doctor's house Cuphead picks the lock on the door so they can wait inside for someone to return to the house (Ch 23).

The brothers spend an entire night in the doctor's house and Mugman gets so bored that he begins examining the various knick knacks and awards around the house. While looking at some newspaper clippings Mugs notices that some of them talk about the doctor's dismissal from the university and gets Cuphead to begin looking through them with him to see if there is any useful information within them. The Cupbros continue looking around the house until Red finally arrives during her normal errands. Cuphead grabs her from behind and threatens her not to try anything before he begins questioning her (Ch 24). While Mugs doesn't speak much during Red's interrogation he does help hold her down while she is tied to the chair. After successfully obtaining the information from the nurse the Cupbros leave Red in the house and head over to the clinic where they quickly find everyone gathered in the cafeteria (Ch 25). The Cupbros immediately open fire on all present and Mugs ends up getting berated by Cuphead when he actually introduces himself to the clinic group. After this small argument there is some fighting between the B-Bros and the Cupbros as the rest of the doctor's group manages to escape further into the clinic. The B-Bros also escape the fight to flee further into the clinic after barring the door behind them to keep the Cupbros out. The Cupbros eventually manage to break down the door and follow after the group. However, before they can catch up with the B-Bros group the police arrives which forces the Cupbros to flee the clinic before they're arrested (Ch 26).

After losing the B-Bros at the clinic the Cupbros procrastinate reporting in for a week before finally heading to one of the seedy bars in town to do it. Cuphead is sure The Devil is going to kill them for the failure but Mugman tries to cheer his brother up, pointing out what they were able to accomplish. The Cupbros head into the bar's basement to give their report and are surprised when it is King Dice who answers the summon instead of the Boss. After giving their report Mugman asks Dice if he'll help them find the B-Bros, too which King Dice eventually agrees to do after negotiating a bit with Cup for a favor in the future. Using his powers King Dice not only find the B-Bros at *Black Hat's Casino* but also discovers their plan to go down to New Orleans to find one of the Parts. Dice then tells the Cupbros about the Voodoo Queen and the Doll, instructing them to go take care of her or get them item if they can since either will help put them back in the boss's good graces. After getting a card of information, a ride to New Orleans on the Phantom Express and the promise that he would take care of the cops looking for them in a couple days King Dice leaves the Cupbros to their new mission. While Cuphead is angry that they now owe Dice a favor Mugman points out that the meeting could have ended in their deaths so Cup should "look at the cup half full". The Cupbros head back up to the bar where Mugman suggests they have a "cup style" drinking contest. Although he ends up losing the contest Mugs has fun and proceeds to spend to rest of the time at the bar arguing good naturedly with his brother (Ch 29).

A couple of days later the Cupbros are walking to an abandoned train station in Toon Town to catch their ride on the Phantom express when the Warner siblings suddenly appear in their path to challenge them to a fight (Ch 32). As the Warners pull both a band and the announcer from Inkwell Isles, Mic, in for the battle Cuphead tries to warn them to just leave because they won't be holding back this time. The Warners don't listen to his warning though and Mic announces the official start of the battle. As they fight the Warner's use various gags against the Cupbros, with Wakko even opening a hole in the 4th wall to a bunch of angry gamers whose angry shouts nearly deafen the Cupbros. While Mugs is confused by what he sees through the hole he is still able to use one of his EX moves to destroy it before the battle continues. After dealing with many more of the Warners gags Cups finally has enough and give Mugs the signal to end it. Using his dodge and another EX move Mugman takes down Dot while Cuphead takes Yakko out of the fight as well. Wakko attempts to stand up to the Cupbros but an Ink Attack stops him in his tracks. The Ink Attack confuses and alarms Mugman, who allows Cup to once again take the lead to take care of the situation. After the battle is over Mugs tries to talk to an angry Cuphead but is just told to shut up. Mugs sadly follows his brother to the train station to catch their ride (Ch 33).

At the train station the Cupbros talk about their home, the 4th wall hole Wakko created and what they're gonna do in New Orleans as they wait for the train. Mugman in particular is scared by what he saw through the 4th wall hole but Cuphead helps comfort him. When the train finally arrives the Cupbros are stopped from boarding by one of the train employee's, Blind Spector. Spector doesn't want to let the Cupbros onto the train due to the fact that they are "breathers", as well as a personal grudge from a past fight with the brothers, so Cuphead tells him to go get the train's conductor to sort it out. The conductor, a giant skeleton named T-Bone, also doesn't really want to let the brothers onto the train but Cup is quick to point out that the train doesn't really have a choice in giving them a ride since it was ordered by King Dice. T-Bone reluctantly lets the Cupbros board the train and, after getting over the unsettling experience of crossing to the Otherside, the Cupbros begin to look for a seat amongst the ghosts. While wandering through the train car they come across Legendary Chalice, who happily invites the brothers to sit with her so they can catch up. Mugman begins chatting with Legendary Chalice about what the Cupbros have been up to since they last saw her, albeit an edited version of events, and bandaging up Cuphead before his older brother eventually falls asleep. After Cuphead falls asleep Mugs and Chalice talk about what's been happening on the Inkwell Isles since the brothers left. After reflecting on his own past with Chalice Mugman also falls asleep with reassurance that Legendary Chalice will wake them when they arrive at New Orleans. Both Cupbros wake up again once they reach New Orleans, where they disembark and say goodbye to Chalice. Before they leave they are also given an address of where they will be staying by Spector from King Dice. The Cupbros head to the address given and are surprised to find it's a river boat run by Ribby and Croaks, two more familiar faces from their past. The two frog brothers also aren't happy to see the Cupbros, much less house them, and Mugs has to pull Cup away before he starts a fight with the frogs. Mugs thinks about how he hopes they can do something fun after they take care of the Voodoo Queen (Ch 34).

The next day the Cupbros head out to find the Voodoo Queen. However they have some trouble finding the address and it's not until Lady Facilier herself shows up and leads them to the shop that they find it. After some talking with Lady Facilier the brothers realize that she is the Voodoo Queen they are looking for. At her invitation the brothers follow her into her shop and sit down at the table in the center of the room there. When Facilier asks the boys to pick some cards Cup says they don't have time for her show, but both brothers are shocked when Lady Facilier reveals she knows about their status as debtors and claims she can help free them. When the Voodoo Queen reveals her price for helping them would be for them to catch an Angel for her Cup says she's crazy. Lady Facilier just tells the brothers to picks cards once again, which Mugs does after being given the go ahead by Cup. After Lady Facilier reads their cards Mugs tries to stand up to fight the Voodoo Queen but snakes burst from the chairs to tie the Cupbros down. Lady Facilier once again asks the Cupbros to work for her but, upon seeing the fear and confusion in Mug's eyes, Cuphead makes the decision to turn down her offer for the both of them. Cup then manages to fire a shot off at Mugs restraints, giving him the chance to escape and start fighting. While Mugs is distracted fighting off the Voodoo Queen's various magical minions Lady Facilier approaches the still bound Cuphead and uses a magical bone knife to transform him into a normal tea cup. Mugs is shocked and enraged by Cups transformation, immediatly demanding that Lady Facilier turn his brother back to normal. However he is unable to defeat the Voodoo Queen on his own and is forced to flee the shop without Cup. As he races down the street Mugman eventually turns into an alleyway where he begins to panic about how he is going to save Cuphead. While he orginally despairs over not being all alone he suddenly remembers the frog brothers are also in town and rushes back to their river boat. He bursts back into the river boat, begging the frog brothers to help him save Cup, but is shocked when they are actually happy to hear about Cuphead's capture. Mugs get's angry at the frogs but they just kick him out. With little time to waste Mugman reluctantly heads back into the city of New Orleans to think up a new plan (Ch 36).

As Mugs travels through New Orleans he is chased by Lady Faciliers shadows, who he manages to lose in a crowd. He attempts to look for Chalice but can't find her anywhere (Ch 40). After a couple days without food he finally eats at a restaurant but ends up not being able to pay for his meal and has to work as a busboy there to pay off his debt, but he keeps getting tripped so he'll break dishes and increase his debt. While working at the restaurant Mugs ends up tripping and breaking some dishes, causing the manager to come out to start berating him. Surprisingly it's none other then the B-Bros who come to his defense, telling the manager off for talking to him like that and even paying off his debt for him. When the B-Bros finally recognize who he is they make a run for it, but Mugs quickly catches up to them using his dodge move and begs for their help in saving Cuphead. Mugs is shocked when Boris actually says he'll hear him out and, after making a quick trip back to the restaurant to pick up his stuff, Mugs and the B-Bros head to a different restaurant where Mugs explains everything that has happened since he came to New Orleans. When Bendy questions Mugs about whether the Cupbros can just leave them alone after helping save Cup but Mugs sadly says that while they can't do that he can let the B-Bros take the Doll and have a head start instead. Bendy continues to try to question Mugs about why the Cupbros are hunting them but the only thing Mugs will tell him is that it's because of the Ink Machine and that they're being forced to do it. The B-Bros go off to discuss amongst themselves and once they return Boris makes Mugs the offer that they'll help save Cup if he promises that him and his brother will leave their friends alone from here on out. After some slight hesitation, Mugs agrees to the deal (Ch 39).

Mugs and the B-Bros plan out their strategy to take down the Voodoo Queen, eventually settling on the idea that Mugs and Bendy will do the fighting while Boris grabs all the items. When Mugs stomach alerts the B-Bros to the fact that he hasn't eaten since the day before Bendy sends Boris off to find a place to eat. Bendy and Mugs have a conversation about choices which causes Mugman to reflect on the choices he has available in his life and how he has made Cuphead responsible for most of the decision making in their lives over the last few years. The conversation then turns to the subject of the B-Bros themselves which continues until Boris comes back to take them to the restaurant he found. When they arrive at the restaurant only to discover that they don't want to serve them since Bendy is a Demon, Mugs stands up for the B-Bros and tells the waiter who refused to seat them that he should be ashamed of himself. After getting some food at a different restaurant the trio head to Lady Facilier's shop to finally take her down. When Mugs and Bendy approach the shop door Mugs is suddenly grabbed by his ankle by an unseen force and dragged into the shop where Lady Facilier is waiting for them. After talking briefly with the Voodoo Queen a shot from Mug's finger gun to the Voodoo Queen frees him and the fight begins. During the fight Mugs gets in close to the Voodoo Queen but a blast of her magic suddenly transports him into what looks like his childhood home. Lady Facilier is also there, transforming him back to how he looked when he still lived in the house and showing him visions of his childhood on Inkwell. The Voodoo Queen once again asks Mugs to work for her, pointing out that it was Cuphead who had turned her down for him last time. Mugman rejects her offer but she then says that she can help him get back home to Elder Kettle again if he does help her. She shows him images of what has happened to Elder Kettle since the Cupbros have been gone, causing Mugs to get chocked up with emotion. When Mugman still tries to decline the offer she tells him to tell it to Elder Kettle, not her (Ch 40).

Mugman panics at the idea of having to talk to Elder Kettle and yells that this whole thing must just be a trick, but Lady Facilier disappears just as Elder Kettle finally notices Mugs. The second Elder Kettle stumbles his way towards Mugman he dismisses all thoughts of illusions and tearfully reunites with his grandfather in a long hug. After both of them apologize to each other about the various mistakes they believed they've made Elder Kettle finally questions why Mugman looks the exact same way he had when the Cupbros left home. Mugs explains that it's just a part of the magic that brought him there. At the mention of magic Elder Kettle invites Mugman to sit down and tell him everything that has happened since he left. While Mugman wants to accept this offer more than anything the obvious space where Cuphead should be pulls him back to the reality of his situation. Mugman sadly but determinedly tells Elder Kettle that he has to go back since he had promised to return home with Cuphead safe and sound so he still had to fulfill his promise. Elder Kettle is saddened to see him go so soon but promises to wait for as long as he can for both Cupbros to return home. After saying their 'I love you's and 'goodbye's to one another Mugman turns to leave the room and the whole scene shatters into darkness. Mugs is awakened by Bendy's voice yelling at him, as he apparently passed out onto the floor when Facilier used her magic on him. Bendy is still busy fighting with Lady Facilier's magical servants and Mugs is immediately pulled back into the battle. When shadowy arms start dragging Mugs towards an ominous looking portal he is forced to use an EX move to free himself, but the recoil from the blast sends both him and Bendy crashing into a wall. This gives the Voodoo Queen the opportunity to pin the two of them against the wall while she deals with Boris. After much struggling Mugs is able to free his hand enough to snap his fingers and change to the chaser bullets, which he then uses to free himself and Bendy. Soon after, Mama Odie arrives and quickly begins fighting the Voodoo Queen herself. While the women are fighting Mugs and Bendy attempt to sneak behind Lady Facilier so they can jump her but get caught by Facilier just as they reach the table in the middle of the room. Bendy ends up accidentally hitting the crystal ball and, noticing how panicked that seems to make the Voodoo Queen, Mugman immediately shoots a string of chaser bullets at it which crack it's surface. Once the crystal ball is shattered Mugman watches in horror with the others in the room as Lady Facilier suffers her terrible fate. After talking with Mama Odie a little bit and a slight scare where Bendy seems like he may drop the transformed Cuphead, Mugs finally gets his brother safely back into his hands. Mugs is distressed that Cuphead didn't turn back to normal after the defeat of the Voodoo Queen and is thinking of how he might be able to get Cuphead back to normal when Mama Odie says she can fix it for him. After some slight hesitation Mugs hands the tea cup over to Mama Odie, who does indeed return Cuphead back to his normal form. Mugs wastes no time in throwing himself at his dazed brother so they can happily reunite. Mugs thanks Mama Odie for her help but when a snarky comment form Bendy alerts Cup to the B-Bros presence in the room Mugman suddenly has his hands full trying to stop Cup from shooting them. When Cups demands to know what the hell Mugs is doing he explains the deal he had made with the B-Bros. When Cup doesn't immediately respond to the news of the deal Mugs rushes to justify himself. Cup asks if this means he can't do anything to Mama Odie and Mugman holds his ground, telling Cup that he can't if he wants to keep the promise that saved his life. While Cup doesn't seem angry about the news of this deal he's not happy about it either as he drags Mugs out of the shop to go find somewhere to eat. When Cup brings up going to the frog brothers place for food Mugs begins to tell him about what happened with the frogs as the two of them make their way back into the city (Ch 41).

### Book Three

Once Cuphead discovers how the frogs kicked Mugman out of their boat he immediately wants to go get revenge. However, Mugman suggested they take two days off to relax from the ordeal with the Voodoo Queen before going after the frog brothers. The two do so and then head to the frogs boat where they not only inform the frogs of their victory against Lady Facilier but also challenge them to a fight, although this fight turns out to be more of a friendly skirmish then a real battle. After winning the fight Mugs stops his brother from taking revenge on the frogs and instead invites them to have a drink with the Cupbros. The four sit together drinking, laughing and catching up on news about the Inkwell Isles. The frogs even apologize to the Cupbros about not helping Mugs and blaming them for their debtor fates, an apology which Mugs gracefully accepts (Ch 47).

Unfortunately, it's right after this apology that King Dice appears to see how the Cupbros have done on their mission. King Dice is furious when he discovers they don't have The Doll, which confuses the Cupbros since he made it sound like The Doll wasn't that important when he was giving them the job. Following this The Devil appears, telling King Dice off for trying to pull a fast one on him before ordering Dice and the Cupbros to come with him. The Devil opens a hole in the ground and instructs them all to jump in. Mugman is terrified by this turn of events but still manages to give a strained smile to the frog brothers for the drinks. Mugs questions his brother with a look on whether or not to jump into the hole and, when Cuphead does jump, follows after him. Mugman ends up landing on top of his brother in one of the storerooms in *Black Hat's Casino*. When he finds out that they are in Hat's Casino, Mugs tries to speak up about leaving quickly like Cuphead wants to but his brother shuts him down. The group walks through the Casino as The Devil explains about the parts, the Ink Machine, The Map and assigns the Cupbros the job of stopping the Ink Machine's activation by any means necessary. After that The Devil and King Dice leave to go take care of other business, leaving the Cupbros alone in the Casino. After a few moments of silence Mugman states how he wishes Cuphead wouldn't pick fights with Dice and once again tries to protest Cuphead's plans to quickly leave the Casino. But once Cup starts walking always Mugman is forced to hurriedly follow. When Cup brings up finding the B-Bros, Mugs seems sad to hear they are back to hunting the brothers but quietly follows after Cup as the two of them head back into Toon Town (Ch 47).

Eventually the Cupbros do track down the B-Bros as they are exiting a cemetery and Mugs is quickly left behind with Boris as Cuphead and Bendy set off on a intense chase down the streets. After the two younger brothers awkwardly stare at each other for a moment Mugs asks Boris if he wants to play go fish. Boris hesitantly agrees and the two boys begin joking and catching up with each other as they play. Boris tells him about Steven and Mugs asks Boris to send a letter back to Inkwell for him since Cup would be mad if he caught Mugs sending it. This gets the two of them talking about their older brothers and Mugs confesses how he sometimes believes Cuphead just views him as a burden. After taking a moment to think Boris replies that there are times he also thinks he's a burden to Bendy but he knows Bendy cares and works hard to do the best for him so maybe Cuphead is the same way, even if he doesn't say it. Mugs thanks Boris for the advice and the two go back to playing but it's not long before they are interrupted by the return of Cuphead, who is carrying an unconscious Bendy under his arm. Cup tosses Bendy at his brother before grabbing Mugs by the handle and dragging his younger brother away (Ch 50).

It's only a few more days before the Cupbros once again track down the B-Bros. While Cuphead is chasing Bendy through an alley Mugman goes after Boris, who was in a bakery at the time. However, while lunging for the B-Bros, Mugman accidentally gets in the way of one of Cups shots and gets hit in his chest. Mugman quickly collapses into a pool of blood as his horrified brother runs over to him. It's not long before Mugman passes out and becomes unresponsive to Cuphead (Ch 53).

While Mugman does not directly appear in the rest of Book Three both he and his brother are brought up during the criminal meeting that takes place in Chapter 57 and in Holly's recap and questioning of Bendy about the contents of this meeting in Chapter 58. They are also briefly discussed during the B-Bros trial whilst examining the events in New Orleans in Chapter 63.
