Penny sells items at a booth in the Toy Zone. She has a grey body with a helmet that covers a majority of her face and her mouth, which resembles a clamshell. The parts of her face that are visible are green, with large eyes.
- Her LEGO version that is contained in 41455 Unikingdom Creative Brick Box gives her a blue body instead.
