I made a challenge for the participants in the Build a Better Monster workshop: make a mouse the size of an elephant. In my original sketch I gave it a long mobile tail (moving the elephant’s trunk onto its bottom), but I later had trouble seeing how that would work. The solution I came up with instead is four giant incisors growing through the skin of the lips, which can be used to gnaw down trees and demolish any smaller plants. A strong, flexible tongue (not shown here) gets food into the mouth. Funnily enough, its lost hair everywhere except the tail, which it uses as a visual signal and fly whisk. A naked mole rat converging on a hadrosaur.
