Yump

Yump, formerly known as Roly-Poly, is a male griffin cub from the Wyoming Menagerie.

Appearance
Yump was described as red with feathers and fur that "were a warm, rusty red tinged with orange around the wingtips". He is bigger than Squorp and Clonk, big enough not to fit inside a backpack, not as tall as Clink, but much rounder than Clink. He has big lion paws.

Personality
Yump has a great love for food, especially cheeseburgers. He is greedy, as in the Wyoming Menagerie and free in Xanadu, he would take as much food at he could get, his gluttonous behaviors disrupting businesses, and the school.

Skills
Yump can communicate telepathically, but he can only be heard by Logan Wilde due to his young age.

The Menagerie
Although not known by name, Yump was the griffin who snuck into Logan's school and ate all of the food in the cafeteria. Yump, while missing, did steal and consume much food in Xanadu, but in his formal appearance, Logan eventually lured Yump to being caught and hit with a tranquilizer dart by enticing him with cheeseburgers.

Dragon on Trial
Yump is mentioned indirectly as one of the griffins that Logan and Zoe had recovered and was now safe.
