| Character Information
Penny's Sister is a minor character in The Amazing World of Gumball. She first appeared for a brief moment in "The DVD" during the chase scene. She makes another appearance in "The Date," along with the rest of her family, this time, with a larger role, where she shows Gumball a tribute picture she made of Mr. Cuddles, her family's pet. When she shows Gumball the picture, he gets scared of it, and stomps the picture to the ground, causing her to start crying and upsetting her family.
Like the rest of her family, underneath her shell, she is a shape-shifting fairy. Her appearance is similar to that of her older sister: antlers on her head, and holes in her shell for her eyes and limbs. Unlike her sister, she doesn't wear shoes, and we have yet to see her and her parents' shape-shifting fairy forms.
As of Season 2 onwards, her face part of the shell is larger then the down part, while in Season 1, it was the opposite.
- In "The Date," she speaks in only single words or short phrases. In "The Spoiler," she is able to speak in complete sentences.
