Mud Girl is the bigger sister of is the eponymous character from the episode Mud Boy. She was originally a drawing Peter made in the mud that "JUMANJI" brought to life in attempt to stop Mud Boy's playtime going overboard, as an allegory of Judy's bossy big sister peronality that Peter dislikes. Like Judy, Mud Girl was also voiced by Debi Derribery.
Personality[]
Because Mud Boy had become overly insufferable and went on a rampage from Peter's rejection of his wishes for an endless playtime, Peter decided that the only one who could stop him would be a mud big sister (who also serves as an allegory to Judy and also drawn in her image).
Role[]
After Mud Boy adds more mud to himself and grows to giant size to chases the three across the dirt mines, Peter finally stops him by creating Mud Girl, Mud Boy's older sister and Mud Girl orders Mud Boy around like Judy does to Peter and gets him to stop attacking the three. Mud Girl orders Mud Boy to give back the mud he absorbed and he has to do what she tells him because she's his big sister and he's her little brother. Mud Boy then returns to his normal size as Mud Girl tells Mud Boy they are going home to play dolls, which he doesn't like but he can't say no to her. The mud children head off home, but not before he gives Peter a friendly wave and appreciates what Peter put on Mud Girl for him: a kick me sign inscribed into her back. Alan realizes that Mud Boy was the "ruin from the earth" and Mud Girl was the "magic birth" thus solving Peter's clue and sending him and Judy back home.
