| Penny's sister
| 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 - she makes a tribute picture 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, Penny's sister is an anthropomorphic peanut. 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, her body is in the shape of an hourglass (though after a season two redesign, Penny gets this as well) and she doesn't wear shoes.
- It is currently unknown what her name is, but it may be revealed in a later episode.
