Mr. Potato Head

**Mr. Potato Head** is a supporting character from the Toy Story franchise.

## Background

A potato toy, his patented design allows him to separate his detachable parts from his body by removing them from the holes on his body. He also has a compartment on his lower back to store extra appendages. He is the only toy shown to be capable of retaining control over his parts, even if they are several centimetres/inches away from his main body, most likely because his toy is designed to be taken apart, unlike many other types of toys, who are typically and effectively "mutilated" when it comes to that. For example, he can still see if his detachable eyes are removed (through the eyes, of course), as well as being able to move his hands and legs if they are detached.

### Development

In the original story pitch for Toy Story, he had largely the same personality as the final film, with his cynicism also being highlighted by his remarking, regarding Buzz potentially falling into the street (after Woody pushed Buzz out of the window, deliberately in this version) that "Buzz ain't going to Pizza Planet now!" He was also shown to be very defensive of his fellow toys, as evidenced by his telling Woody, after the latter viciously insulted Slinky Dog and threatened to throw him off the bed for not willing to obey him in throwing them off the bed, that he might as well throw him off as well, with Hamm, and Rex joining in.

### Personality

Mr. Potato Head is a rather cynical Mr. Potato Head doll, of the common design of Playskool. Andy often casts him as a villain in his games, which seems to be the reason for his cynical and irritable behaviour. Even though he is sarcastic, cynical, rude (mostly to Woody at first), and has an acerbic point of view, he has a good heart deep down, he loves his wife Mrs. Potato Head, and is prepared to go to limitless lengths to save his friends. In the second film, when Woody was kidnapped, he showed some shock and later showed some sadness when Woody refused to go back home. Mr. Potato Head appears to be partners with Hamm as they are seen high-fiving each other whenever something exciting or victorious happens.

Despite having more of an attitude in Toy Story, he becomes much more amicable after the arrival of Mrs. Potato Head.

Despite his grumpy behaviour, Mr. Potato Head can sometimes be fun-loving with a genuine sense of humour.

## Film Appearances

### Toy Story

Mr. Potato Head first appears in Toy Story, playing One-Eyed Bart. After Andy leaves his room, Mr. Potato Head wakes up to find a number of his parts scattered to the floor (Molly has earlier drooled on him and smashed him apart), also expressing irritation that Andy placed him in Molly's crib during their "playtime" as he is supposed to be only playable for children of ages three and up. He then shows Hamm his messed-up face (with all his facial pieces, except his moustache, in the wrong slots), pretending to be Picasso, but Hamm is confused and Mr. Potato Head berates Hamm for being uncultured.

When Woody holds a staff meeting, Mr. Potato Head asks if they have to hold hands when Woody tells everyone to get a moving buddy. Mr. Potato Head points out that Woody is, of course, not worried when he tells everyone not to panic when Andy's birthday has been moved to that day, citing bitterly that Woody has been Andy's favourite since kindergarten, only for Slinky to speak up to Mr. Potato Head when he has complained about that, and when Slinky is not looking, Potato Head takes off his mouth and "kisses" his own butt while Slinky keeps talking. When Woody sends Sarge and his Green Army Men, Mr. Potato Head prays for Andy to get a Mrs. Potato Head.

During most of the first film, Mr. Potato Head is rude and mean to Woody mostly because he is jealous of Woody being Andy's favourite toy. For example, when he becomes fascinated with all the features of the Buzz Lightyear action figure that Andy has received for his birthday, Mr. Potato Head makes fun of Woody by accusing him of not having a laser-like Buzz, describing Woody's sampled voice "like a car ran over it" and suggesting an attic as a special place Andy will have for Woody.

One evening, after Woody accidentally knocks Buzz out the window, Mr. Potato Head is quick to accuse him of being a murderer, having witnessed the chain of events that led to it, and interrogates Woody as to if he will do the same to him as well if Andy started playing with him more. Before Woody could reply, Hamm, having seen everything as well with Mr. Potato Head, decides not to give Woody that chance and agrees with Mr. Potato Head. The two of them then lead a mutiny with the other toys to attack Woody, despite and Slinky and Bo Peep's attempts to talk them down and defend Woody. But before the toys can do so, they all retreat when they hear Andy approaching the room. While Andy searches the room for Buzz, Mr. Potato Head quietly gets Woody's attention and has Etch A Sketch draw a hangman's noose, threatening to hang Woody for harming Buzz, before Andy leaves with Woody for Pizza Planet.

That night, when Andy and his mother return home, Mr. Potato Head, along with Hamm, feel somewhat content when the toys learn about Woody's disappearance, taking it as an establishment of Woody's guilt in the window incident.

The next day, Woody throws a string of Christmas lights from Sid's house to Andy's house; Slinky catches them, but Mr. Potato Head snatches them away and labels Woody a liar after reminding the others about the window incident with Buzz. Woody then tries to convince the toys to let him get back by pretending that Buzz is with him (using Buzz's severed left arm), but Mr. Potato Head remains suspicious of what Woody is actually doing and asks Woody what's he trying to pull. When Woody accidentally blows his cover by showing Buzz's arm, Mr. Potato Head snaps at Woody, calls him a "murdering dog", and tells him that he hopes Sid rips his voice box out before the toys back away from and close the window, leaving Woody and unknown to them, a still-alive Buzz, stranded in Sid's house. Even Bo Peep or Slinky start to lose their faith in Woody and start to actually believe Mr. Potato Head and Hamm were right at this point.

On the night before the moving day, it was shown that Rex was his moving buddy, but only because everyone else was picked. Rex sticks his head out of the box to gasp for air, making Mr. Potato Head angry and wonder why they became moving buddies in the first place. Rex then told him that everyone else was picked.

The next day, during the move to Andy's new house, Woody tosses RC out of the moving truck onto the street to rescue Buzz from Scud. Thinking Woody is trying to kill another toy, Mr. Potato Head rallies the others to ambush and toss him overboard, despite that Andy already missed Woody. During the ambush, Woody hits Mr. Potato Head with RC's remote, making his left ear and entire face parts fall off and his mouth yells, "Toss him overboard!" after Woody tries to explain to the toys that they need to save Buzz. However, when Bo Peep reveals that Woody was telling the truth after the other toys see Woody and Buzz on RC, Mr. Potato Head realizes his mistake and is horrified and guilty at his actions. He tries to compensate for his mistakes by holding onto Slinky's tail so Slinky can help Woody, Buzz, and RC back into the truck. It unfortunately fails, but Woody gets an idea and uses Sid's rocket and tosses RC back to the van; the toys move out of the way as RC crashes into Mr. Potato Head, sending his pieces flying in all directions, possibly as an ironic payback for having led the mutiny in the first place.

At the end of the film, Mr. Potato Head seems to be in a better mood. He is excited to hear Molly receiving a Mrs. Potato Head as her Christmas present. When Hamm congratulates Mr. Potato Head, he remarks he had better shave, so he removes his moustache.

### Toy Story 2

In Toy Story 2, he is first seen having found Mrs. Potato Head's missing ear. Woody thinks he found his hat, but he tells Woody that Mrs. Potato Head lost her earring as he returns it to her. Along with the other toys, Mr. Potato Head witnesses Woody going down to the yard sale with Buster to rescue Wheezy from being sold and is shocked when Woody gets stolen by Al. After Woody is kidnapped, he and Hamm set up a crime scene, where Mr. Potato Head operates Exhibit F, in which he details the kidnapper's escape route, though he later snaps at Rex after the latter, when asking for the phone number for the FBI, accidentally destroys his crime scene. He indirectly (and inadvertently) helps Buzz deduce the answer to LZTYBRN (the license plate on the car of the thief) when he sarcastically tells the others to "leave Buzz to play with his toys". As Buzz tells Etch to draw the man in a chicken suit, Mr. Potato Head, along with the other toys, is horrified to learn that the man who has kidnapped Woody is the "Chicken Man", Al McWhiggin, who also happens to be the owner of Al's Toy Barn.

Later, Mr. Potato Head goes on a mission with Buzz, Slinky, Hamm, and Rex to save Woody, showing him in a much more positive light and suggesting that his relationship with Woody has greatly improved. Before they leave, Mrs. Potato Head packs her husband an extra pair of shoes and angry eyes and Mr. Potato Head puts on his moustache he "shaved" saying, "Let's roll." At one point, when the toys are reprimanded by Buzz for requesting a rest, Buzz mentions the time when Mr. Potato Head had Woody thrown out of the back of the moving van and Mr. Potato Head is still shown to be regretting this greatly, even though Woody has long since forgiven him. When the toys cross the street to Al's Toy Barn, they indirectly make a semi tractor-trailer jack-knife, and the chains securing a large pipe on the semi break, freeing the pipe. The pipe subsequently rolls down the street, during which Potato Head gets one of his feet stuck on a piece of chewing gum on the pavement. He manages to free his foot from the gum and narrowly escapes getting rolled over by the pipe. Upon making it to the other side of the road, he commented on how well that went, just as the pipe rolls into and makes a lamppost fall down onto the street.

While the toys search Al's Toy Barn, they encounter a Barbie aisle, where Tour Guide Barbie hops into the car right next to Mr. Potato Head, who reminds himself he is a married spud, prompting Hamm to switch seats with him. He seems to be the most suspicious of a cocky attitude of the newer Buzz that the toys take with them from Al's Toy Barn. After the toys break into Al's apartment, the newer Buzz uses Mr. Potato Head's eye to scan the room and sees Jessie tickling Woody, but they mistake this for actual torture. After smashing Rex's head through the air vent, Mr. Potato Head tries to scare Jessie by reaching into his back compartment for his angry eyes, but accidentally attaches his spare pair of shoes (especially after Mrs. Potato Head has given him his shoes and his angry eyes).

When the toys leave the apartment after Al leaves with Woody, Mr. Potato Head throws his hat like a frisbee to jam the apartment lobby's closing doors, letting the toys pass through. Outside, he is the first to spot an idling Pizza Planet delivery truck nearby and is assigned by Buzz to operate the levers and knobs with Hamm. To make the truck accelerate, Mr. Potato Head shifts the lever of the truck while Slinky presses down the pedals. While the toys chase Al in the truck, Mr. Potato Head saves three alien toys from flying out the window. He becomes increasingly annoyed at the aliens' repeated expression of their gratefulness towards him. At Tri-County International Airport, he, Hamm, Rex, and the Aliens aim for luggage identical to the one the Roundup Gang are trapped in, only to find flash cameras instead. However, they use the cameras to stun a traitorous Stinky Pete before he can finish Woody off with his pickaxe.

After the toys return home, Mrs. Potato Head, upon hearing that her husband has saved the aliens, decides to adopt them as their children, much to his dismay. Finally, he and his wife stand together as they watch a fixed Wheezy sing (in a deep voice) "You've Got a Friend in Me."

### Toy Story 3

In Toy Story 3, Mr. Potato Head has become distrusting of Andy, thinking he no longer cares for his toys as a result of growing up. Despite this, he tries to comfort his wife while the Aliens try to find comfort in him as well — much to Mr. Potato Head's annoyance. Eventually, Woody declares it's time they "close up shop" and prepare to live the rest of their days in the attic, which Mr. Potato Head and the others lament. Unfortunately, they are mistakenly thrown out by Mrs. Davis. This infuriates Mr. Potato Head and the other toys, who unanimously decided to donate themselves to Sunnyside Daycare.

Though things seem pleasant at first, the leader of the daycare Lotso tricks the toys into becoming members of the Caterpillar Room, where they are mangled and tormented by toddlers. After learning that Andy actually still wants them, and that Woody was right all along, Hamm starts scolding Potato Head for not believing him in the first place (which was not used in the first movie for everything he had done), which leads to a brief argument between them both of who didn't believe Woody first. The toys band together to return home, only to be stopped by Lotso, his henchmen, and a reset Buzz. Potato Head defends his friends by mouthing off Lotso, which results in the former being sent to the box as punishment. The next day, Potato Head is reunited with his wife but is sandy and in a haze. Woody returns later that day, and Potato Head indirectly confesses that he was right about Andy.

They form an escape plan, in which Mr. Potato Head purposefully gets himself put into the box. He escapes by dismantling himself and assisting the others outside the daycare building. He uses a tortilla to replace his body, but it is eaten by a bird. This forces Mr. Potato Head to instead use a cucumber from the daycare's garden. However, after the rest of the toys are freed, Mr. Potato Head is reunited with his old body.

Together, the toys escape the daycare and Lotso's clutches but are accidentally taken to the dump and nearly face incineration. They are saved by the Aliens, who Potato Head finally accepts as his children out of gratitude. Back at Andy's house, Mr. Potato Head and the others accept their future as attic toys, but Woody manages to get everyone donated to a young girl named Bonnie instead.

### Toy Story 4

Mr. Potato Head appears once more in the fourth movie, though like many of the other toys, he has a very small role in the ultimate story. He also has very limited dialogue in the film due to the death of Don Rickles in 2017 in which archived/unused dialogues of Rickles were used.

He first appears in the flashback 9 years prior to the third and fourth film. During a thunderstorm, Andy comes in and dumps the rest of the gang onto his bed to head downstairs for dinner. After he leaves, the toys jump up and begin to panic because Andy accidentally left RC outside in the thunderstorm. Woody tells Buzz, Jessie, and Slinky to follow him to Molly's room while the rest of the gang stays put. It can be assumed Mr. Potato Head was saddened by Bo Peep's departure after being sold off to another owner. He is later seen throughout the "You've Got a Friend in Me" sequence, being played with by Bonnie.

Nine years later, Mr. Potato Head now lives with the rest of the toys with Bonnie being their new owner. He first appears with the rest of the toys waiting in the closet for Bonnie to finish her breakfast. The toys are cramped and annoyed with one another, with Mr. Potato Head asking someone where his ear is. Once Dolly shushes everyone, he is heard snickering after he jokingly presses Buzz's buttons to break the silence, much to Buzz's annoyance. He, along with many of the other toys, is played with more prominently than Woody, who Bonnie neglects. When Bonnie arrives in her room, she plays "town", and takes the whole gang out except Woody. He watches in sadness as the other toys are played with by Bonnie, with Mr. Potato Head's hat being put on Bullseye while they play "Hat Shop". Suddenly, Bonnie's father walks in and tells her to get ready for kindergarten orientation, much to her dismay. When Bonnie asks if she can bring a toy (namely Jessie) with her, Mr. Anderson says toys aren't allowed in school. After they leave, the toys (including Mr. Potato Head, who tries to grab his arm off the floor) are about to get up when Dolly tells everyone to freeze, since Bonnie always forgets something and could be back any second. After seeing Bonnie crying under her bed when she returns into the room, Woody decides to sneak into her backpack to keep an eye on her, much to the other toy's dismay. During her orientation, she creates Forky, a spork who suddenly comes to life.

When Bonnie returns and drops her backpack off in her room, Woody climbs out and is scolded by the rest of the gang for breaking the rules, with Mr. Potato Head saying he knew Woody would sneak out. But Woody alleviates the situation by saying that not only did Bonnie have a great day in class and they're all going on a road trip, but Bonnie made a literal friend in class. Woody pulls out Forky and introduces him to the gang. Like the others, Mr. Potato Head is both shocked and confused by both Forky's existence and his love of trash. They then watch in confusion as Woody fishes Forky out of the trash, saying how he'll keep an eye on his during the road trip.

Mr. Potato Head is then seen throughout the "I Can't Let You Throw Yourself Away" sequence, sitting still as Woody frequently keeps Forky from throwing himself out. That night, while everyone else is asleep, Forky escapes out of Bonnie's hands and jumps out the RV window. Woody says he'll meet them at the RV park in the morning with Forky and jumps out the window.

The next morning, the toys sneak a spoon into a sleeping Bonnie's hand as a substitute for Forky, but to no avail, as Bonnie is distraught over losing her favourite toy. As she goes outside with her parents to look for him, the toys contemplate on what to do. Buzz (after listening to his "inner voice", AKA his voice box) then states he must go, to which Mr. Potato Head asks what happens after that. Buzz then states there's no time to explain and jumps out the window to find Woody and Forky, leaving the other toys to make sure the Andersons do not leave the RV park. Meanwhile, Woody talks to Bo Peep (who is now a lost toy and helps Woody rescue Forky from the Antique Store) mentions to her how the whole gang is still together, including Mr. Potato Head.

That afternoon, the gang begins to panic as the Andersons prepare to leave with Buzz, Woody, and Forky still out there. Rex begins to have a panic attack, and accidentally knocks into Mr. Potato Head with his tail, causing him to lose some of his parts, and Mr. Potato Head tells Rex to watch it. He remains unimpressed with the toys' ideas, rolling his eyes when Rex suggests they could go back in time to warn Woody about the future. While they struggle to think of a plan, Jessie quickly leaps out of the window and pops the front tire of the RV, much to the group's relief.

By that night, Mr. Anderson finally fixes the tire, but Buzz arrives just in time. Buzz explains to the gang that he and Woody must be extracted from the Antique Store. As the Andersons climb into the RV, the toys collapse. Buzz whispers to the gang that Bonnie will realize she left her backpack back at the store and they will go back for it. But apparently, Bonnie doesn't notice and the RV begins to drive off. Buzz then uses his voice box and his "inner voice" once again to think of a plan. Mrs. Anderson believes Buzz to be broke and throws him in a drawer when Buzz quickly yells out to Bonnie (in a way to sound like one of his phrases): "Your backpack is at the Antique Store; let's go!" This works, and the RV turns around to return to the Antique Store.

After getting her backpack with Forky inside, Woody sneaks off to help Gabby Gabby and tells him to get the RV to the carousel as a meet-up spot. While Bonnie is sleeping, Forky explains it to the gang, to which Mr. Potato Head is sceptical on how to get the RV back to the carnival. Jessie then comes up with a plan. Buzz climbs to the roof and tells Mrs. Potato Head where to go using her ear. Meanwhile, Mrs. Potato Head hides under Mr. Anderson's seat and repeats the directions to Trixie, who mimics the GPS in order to tell Mr. Anderson where to go. When the plan begins to fail, Buttercup then sneaks under the gas pedal and pulls it forward so the RV can go faster, eventually making the RV be chased by the police.

After successfully getting to the RV to the carousel, Buzz tells everyone to get to the roof while Forky locks the Andersons out of the car after dealing with the police chasing them. After stacking themselves up, Mr. Potato Head (at the top) uses literally both of his arms to open up the awning as a bridge between them and the carousel. They soon climb up and the older toys are shocked to see their old friend, Bo. As the other toys realize that Woody is going to leave them to be with Bo, he and Mrs. Potato Head give a content grin, understanding his reasons to stay with her. Woody is then given a group hug joined by Potato Head. Forky sneaks up to join them but leaves the doors unlocked, causing the RV to pull away. After jumping back into the RV, the gang watches as Bo and Woody wave goodbye on top of the carousel.

One year later, Bonnie drops off her backpack after her 1st grade orientation. Jessie emerges from the bag and is barraged with questions by the other toys. Jessie interrupts everyone by saying Bonnie made another new friend and introduces the gang to Knifey, a toy knife Forky falls in love with.

### Short Films

#### Toy Story of Terror!

Mr. Potato Head returns in the Halloween special.

He is shown watching an old movie on a portable DVD player with the rest of the gang in the Andersons' trunk during a stormy night. Mr. Potato Head calls the movie boring. Mr. Pricklepants explains that all great horror films start slowly, only for Potato Head to pull off his ears while Mr. Pricklepants goes on a lecture. He is later shown helping the other toys rescue Jessie out of a toolbox after she fell in from the impact of a flat tire. After the others comfort her due to her claustrophobia, Trixie quietly asks what is wrong with Jessie, to which Mr. Potato Head explains she was abandoned and put into storage for years. After they run into Bonnie's bag, they see Bonnie and her mother walk into a hotel due to the car having a flat. Trixie eavesdrops the conversion with Mrs. Anderson on the phone, saying that the tow truck will not come until the morning, meaning they will have to stay at the hotel all night.

After Bonnie and her mother fall asleep, Mr. Potato Head sneaks out of the suitcase to look at the free amenities, claiming he promised Hamm that he would bring back something nice. Mr. Pricklepants warns him to not go out there, since "the first to leave usually gets it", but Woody warns him not to leave since a hotel is one of the easiest places for a toy to get lost. Mr. Potato Head disagrees and leaves, making the rest of the toys walk out to check the free stuff. He then mysteriously disappears, being taken away by a mysterious creature.

After going under the hotel through a vent, Trixie, Mr. Pricklepants, and Rex are taken by the creature, leaving Woody, Buzz, and Jessie to remain. The trio then find Mr. Potato Head's arm, which they use as a compass to find the way. Woody and Buzz are taken by the creature, with Potato Head's arm being swallowed by it. After snatching Combat Carl and cornering Jessie in a shower, it's revealed that the creature is an iguana named Mr. Jones. He snatches Jessie and brings him to his owner, Ron the hotel manager. Ron uses Mr. Jones to sneak into his customers' hotel rooms and steal toys and valuables, where Ron then sells them online.

After putting Jessie in a locked bookcase, she reunites with both her friends and another group of kidnapped toys. After a failed attempt to open the lock with a paperclip, Ron's computer gives an alert, saying that he has a sale. It's revealed Woody has been bought online for a large price, making Ron package him and puts him with other packages. After Jessie is also bought, she is left outside the case after Ron gets distracted with the tow truck company. Jessie cannot reach the lock, and says she will get Woody so they can reach the handle together. But before she can, a delivery lady arrives and takes the package Woody is in. Combat Carl then encourages Jessie to sneak into a box so she can rescue Woody out of the truck. After accidentally getting sealed into the box by the delivery lady, Mr. Potato Head gives up, saying that they're never going to get out of there. After a while, Trixie doubts that they're coming back, but Mr. Pricklepants claims to be patient, using a movie's tension as an example. This causes Mr. Potato Head to snap and say that life is not a movie and that Jessie and Woody were not coming back, only for them to run in through the vent moments later.

Before Jessie stacks herself on top of Woody, she sees Bonnie and her mom checking out behind the curtains. She then comes up a plan to pull the curtains to reveal the toys in the shelf, but gets stopped by Mr. Jones. During a struggle, Jessie realizes that Mr. Jones has a weak gag reflex after puking up Combat Carl's arm. She then throws herself into his mouth, where she pulls out Mr. Potato Head's slobbery arm. As Mr. Jones pulls Jessie away, she uses the arm as a grip for the curtain, making it fall down. Bonnie sees her toys inside the case before she can walk out and runs into the back to grab her toys. After Mrs. Anderson threatens to call the police, she grabs Bonnie's toys and walks out with her daughter. The gang thank Jessie once back in the trunk. But Rex asks frantically if anyone has seen for Mr. Potato Head and Mr. Pricklepants says that Mr. Jones must have claimed "one final victim", only for Jessie to calmly say he is still here. He is shown kissing his arm, saying they will never be separated again, only for the force of the car to eject all of Potato Head's parts and making them scatter, making the gang laugh.

#### Toy Story That Time Forgot

Mr. Potato Head returns in the Christmas special. He spends Christmas with Bonnie and her toys. His role is smaller than his role in the films and Halloween special.

## Television Appearances

### Toy Story Toons

Mr. Potato Head appeared in the series of shorts, primarily playing a minor role.

In "Hawaiian Vacation", he is shown to be excited with the rest of the gang since Bonnie is flying to Hawaii for a week for her winter break. When Buttercup asks if he is joining him, Hamm, and Chuckles in a game of cards, Mrs. Potato Head speaks for him and says he is all hers for the vacation. Mr. Potato Head awkwardly states that the two will have fun weeks together, only to throw his eye and arm into the game so he can play. When Barbie and Ken arrive into Bonnie's room, they think they're in Hawaii, only for Woody to say they are in Bonnie's room and that Bonnie left her school backpack at home. While Ken hyperventilates, Mr. Potato Head questions his logic for thinking Bonnie would take her school backpack on vacation. Ken then cries inside Bonnie's backpack, while Barbie tells the gang Ken had been planning a romantic getaway for them for months. When she sadly says how they were planning to have their first kiss, Mr. Potato Head asks out loud they still haven't kissed yet, only to be harshly shoved by Mrs. Potato Head and making his parts collapse. The gang then hatch a plan to give Barbie and Ken the vacation they deserve by making a make-shift Hawaiian resort in Bonnie's bedroom. Mr. Potato Head acts as the hotel's concierge and sticks his parts into a literal pineapple during a "Guided Nature Hike" with Barbie and Ken. He is then seen making a make-shift beach for Barbie and Ken to kiss by standing on top of Trixie and dumping cat litter in front of a picture of the beach. Slinky then yells out that Barbie and Ken are outside on the porch. The gang watch happily as Barbie and Ken share their first kiss, only for the two to fall into the snow. The gang are then seen getting Ken and Barbie out of a frozen icicle, with Mr. Potato Head using a screwdriver as an ice pick.

In "Small Fry", Mr. Potato Head is seen in the background, where he and his friends meet a miniature Buzz Lightyear.

In "Partysaurus Rex", Rex accidentally pops the bubble Mrs. Potato Head was blowing, prompting Mr. Potato Head and the others to poke fun on Rex by calling him "Partypooper Rex." This also led to him being indirectly responsible for Rex holding a party in the bathtub and calling himself "Partysaurus Rex." After the plumber came over due to the water overflowing thanks to Rex (resulting in Mr. Potato Head removing his ears temporarily to let the water inside spill out), Mr. Potato Head was in disbelief that Rex could hold an effective party until the pool toys invited him to cause a rave.
