1: [Young]
To young Thumpies the whole world is a bouncy castle. For these tumblendy-twins have an instinctive need to tumble and thump. Thumpies must never be subjected to polka music or velcro...
2: [Adult]
Thumpies bring their musicality and infectious sense of fun to each world they explore, spreading mischief and colorful hairballs everywhere they go. Though their skin is tough as rawhide. Their fur is fine as spider silk-and a tad adhesive-so they make excellent lint brushes should the need arise.
3: [Prismatic]
These Thumpies returned form the Prism Gate forever changed! Curiously, the FurFace and NooBie subspecies were swapped with - and their stump altered at the molecular level to become a fanged creature with beady eyes - extraordinary!
