==Synopsis==
Ma Vreedle threatens to blow up the sun if Ben and the Plumbers don't find her missing son!
==Plot==
At the Bellwood Museum, the Vreedle Brothers are seen stealing pipes and equipment. Ben and Rook suddenly arrive, where they and the Vreedle Brothers are surprised to see one another. Rook immediately attacks Rhomboid, while Ben transforms into Four Arms and lifts up Octagon. However, his mom, Sandra Tennyson, calls his phone. Octagon pokes fun at Four Arms and he responds by throwing Octagon on the ground. As Four Arms continues to talk to his mother, Rhomboid throws a bear trap at Rook's Proto-Tool. After hanging up, Four Arms begins to chase the Vreedle Brothers. Rhomboid then throws a grenade, forcing Four Arms and Rook to hide in a nearby dumpster. Strangely, no explosion is seen, and Octagon reveals that Rhomboid still has the grenade in his hand and only threw the key. The grenade explodes, completely blowing up the Vreedle Brothers. After Four Arms transforms back into Ben, Rook goes to inspect the crater while Ben talks to his mother again. Sandra reminds Ben that he is coming home for dinner and even asks to bring Rook with him, saying that he loves her cooking. Ben agrees and hangs up. Rook grabs Octagon's hat and says that they have met the Vreedle Brothers for the last time, though Ben doesn't think so.
Somewhere in Undertown, a container opens, revealing another set of clones of Octagon and Rhomboid. Rhomboid recalls having been blown up and wonders how they are still alive. Octagon responds that whenever they die, their memories get transferred into another set of clones. Suddenly, the Vreedle Brothers are tied up by Ma Vreedle, who says that they have kept their younger brothers starving. She orders them to watch over the Pretty Boys while she gets the food. The Pretty Boy Vreedles seem excited to see Octagon and Rhomboid, until one of them slaps them both with his lollipop. The other Pretty Boys all stick their lollipops onto the Vreedle Brothers and stick them both onto the cloning pod. 
At Ben's house, Ben and Rook are preparing to eat Sandra's food. When Sandra says that she made Ben's favorite, Ben thinks of chili fries but it's just steamed tofu and wheat germ with algae. Rook compliments the food and Ben hands Rook the rest of his food. Back at the Vreedles' home, Ma Vreedle is feeding all of her Pretty Boys her cooking. The Pretty Boys gladly eat the food and Ma Vreedle stops Octagon and Rhomboid from taking any. Ma Vreedle then says that they are poor criminals and walks off. Octagon then has an idea, saying if he and Rhomboid had a third member, they would stand a chance. Rhomboid states he doesn't trust anyone that isn't a relative, but Octagon reminds him that they have plenty of relatives and recommends taking one of the Pretty Boys. The Vreedle Brothers take one while Ma isn't looking and give Ma a kiss goodbye before leaving. Rhomboid worries that Ma Vreedle will get upset over her missing son, but Octagon says that she has so many Pretty Boys that she wouldn't notice one missing.
Back at Ben's house, Rook has finished his (and Ben's) food and gets a call from Magister Patelliday, saying something is on a rampage. Ben then tells Sandra that he needs to go out again and leaves quickly with Rook. At Plumber Headquarters, the Plumbers are at the wrong end of a rampaging Ma Vreedle. She demands to know where her missing Pretty Boy is. Ben and Rook arrive at the scene and are surprised to see her. She chucks a large piece of stone at them and they dodge. Ben transforms into Bloxx. Bloxx charges at Ma and she attempts to cut him off by firing blasts at him. Bloxx knocks away the blasts and attempts to contain her. She shoots her way out and knocks Bloxx downward and crushes him. Bloxx thinks she is talking about the Vreedle Brothers, but Ma Vreedle says she is talking about one of her Pretty Boys. Magister Patelliday ensures Ma Vreedle that the Plumbers don't have her Pretty Boy and she says she knows and wants the Plumbers to find him for her. Bloxx transforms back into Ben, and Ben is shocked to see that she is there to report a crime instead of commit one. Ma Vreedle says that even though she is a criminal, she hopes that the Plumbers will help her, as she is a mother looking for her missing child. Magister Patelliday agrees and wants a description of her Pretty Boy and she shows him a picture of him (even though the others look exactly the same). Ma Vreedle demands that Ben and the rest find her Pretty Boy or they will lose their sun. Ben thinks she's bluffing, but Patelliday says that she is wanted in 12 systems, banned in 27, and rumor has it that she made even Vilgax cry. Ma says she already has a rocket ready to smash into the sun and Patelliday tells Ma that they will find her son. Rook doesn't think that it was a good idea letting her go, but Ben shows that Patelliday placed a tracking device on her, which leads right to her rocket. Patelliday says he will locate the rocket while Ben and Rook track down the missing Pretty Boy. Sandra once again calls Ben, saying she has his leftovers, but Ben quickly leaves.
In town, Rook drives the Proto-TRUK, while Ben calls out for Pretty Boy. Suddenly, a large explosion is seen at the Bellwood Bank. Rook drives around the Vreedle Brothers with the missing Pretty Boy Vreedle, and the three of them run from the bank. Rhomboid asks why they blew up the bank if they were robbing the candy store, and Octagon says that they were "multi-tasking". The Pretty Boy is seen with candy and eats it. Rook confronts them, and when Rhomboid attempts to attack with some dynamite, Kickin' Hawk suddenly attacks him and Octagon from behind. Rook is surprised to see them still alive, and Octagon activates the dynamite. Kickin' Hawk quickly grabs the dynamite and kicks it into the sky before it explodes. The Pretty Boy tosses his lollipop at the candy store sign, and it crushes Kickin' Hawk and Rook. The Vreedle Brothers escape with the Pretty Boy and Kickin' Hawk receives another call. Kickin' Hawk cannot answer the phone due to his claws, so Rook answers it instead. After Kickin' Hawk transforms back into normal, Rook says it's "Ma" calling and Ben answers the phone, thinking it's his mother. It's actually Ma Vreedle, asking if Ben has found her son yet. Ben says he hasn't yet, and she warns Ben that he has until sunset to find him, or she'll destroy the sun.
At Undertown, the Vreedle Brothers are preparing their greatest criminal undertaking. Rhomboid wants to destroy the entire universe, but Octagon says that they need better firepower for that. The Pretty Boy Vreedle then starts to say, "boom boom" and Octagon now knows that their mother may have that kind of firepower to blow up the universe. Back in Bellwood, Ben and Rook are having trouble finding the Pretty Boy. Ben then notices "mom" in the mirror and Rook think it's Ma Vreedle. Ben says that it's his mother and is afraid of eating her leftovers. However, she loses sight of them. At the Vreedles' home, the Vreedle Brothers are moving something in a wheelbarrow. Octagon notices Ma coming and tells Rhomboid to hide the Pretty Boy. Ma is getting more and more worried about her missing son and opens a container, revealing the rocket. Somewhere underneath, Magister Patelliday manages to locate Ma and she is seen on the rocket on a train, getting ready to destroy the sun. Patelliday then calls Ben and Rook, saying that the rocket is on the train and Rook (now flying the Proto-TRUK) chases after Ma Vreedle. 
Ben gets onto the train and Ma Vreedle summons fully grown Pretty Boys to fight him. Ben transforms into Ditto and uses his clones to attack the fully grown Pretty Boys. The attack doesn't faze them and they easily begin to overpower the Dittos. Rook then gets out and begins to fire at the Pretty Boys and knocks them off the train. The Pretty Boys come back up and Ditto tells Rook to get down below. The Pretty Boys are knocked off the train by a low pole and Ma Vreedle begins to fight Ditto and Rook herself. She fires a large blast between the train causing it to split in two. Her end quickly gets away, but Ditto manages to get on by using his clones for leverage. Ma Vreedle and the Dittos get into the train and the Dittos find themselves surrounded by more grown-up Pretty Boys. The Dittos merge back into one and manage to trick all of the Pretty Boys into going out the train and Ditto transforms back into Ben. Ma Vreedle is excited to see the missile flying toward the sun and Ben tries to get an alien through the Omnitrix. The missile appears to be a dud and Ma Vreedle quickly finds out that it was the Vreedle Brothers' doing.
At Max's Plumbing, the Vreedle Brothers with the Pretty Boy are seen with the missile part trying to find out how to make it explode. Rook arrives and urges them not to make it explode or it will destroy them and the Earth. Rook quickly blasts Octagon and Rhomboid, but the Pretty Boy Vreedle knocks him down. Sandra arrives at the scene and Ma and Ben soon as well. Ma is excited to find her missing Pretty Boy while Ben tells his mother to get away. Sandra wants to know what is happening and Ma threatens to blow up the Earth. Sandra yells at Ma, not wanting her to destroy the Earth with Ben in it, which is enough to convince her. Ma Vreedle then yells at Octagon and Rhomboid for taking her Pretty Boy and her warhead but praises them for doing something evil. Octagon wants to know why he and Rhomboid are different in appearance while all of the other Pretty Boys are exactly the same. Ma says that the Vreedles come in different shapes and Octagon says that there must be a shape name for the Pretty Boy they had with them. Sandra suggests naming him Dodecahedron and he likes the name (calling himself Dody). Ma is pleased to see her son liking the name and Sandra hands over Ben leftovers. Ma says that Octagon and Rhomboid did a good job looking after the Pretty Boys that she wants them to continue to watch over all of them. The Pretty Boy Vreedles then start to move toward them.
