Princess

Princess is a female Chain Chomp who appears in Paper Mario: Color Splash. During the game, she and her owner, the Professor, go for a walk through Mondo Woods but never return. When Mario finds the Professor weeping in the woods, it's revealed that Princess had escaped from her chain and ran away. After Mario and Huey reach Marmalade Valley, it is implied that Princess had grown to huge proportions as a side effect of the magic Kamek had used to do the same to Mondo Woods. After escaping her destructive attack through the construction site, Mario and Huey must use the Cutout technique in Château Chanterelle and the Bone Thing card to bait her back home. She acts very similar to a Chomp after growing huge.

Princess reappears when using the Bone Thing card on an enemy, where she rolls over and damages them to get the bone.

She also briefly shows up during the Toad celebration in Port Prisma after Mario collects the Yellow Big Paint Star.

There are also pictures of Princess when she was smaller in the Professor's house at Château Chanterelle, which show her and the Professor playing. The design in these pictures resembles the design of Chain Chomps in Paper Mario: The Thousand-Year Door, as opposed to the more recent Paper Mario: Sticker Star, due to the lack of trapezoid-shaped connector between the chain and body.
