Tumblar

A furry round creature with short legs and arms. It gets its name from its tendency of rolling itself up into a ball and tumbling down all sorts of slopes and other downhill locations.

Tumblars don't have neck, their faces being part of their bodies' middle region, allowing for better protection when they are rolling downhill. Their furry coat isn't just for warmth purposes either, working as a cushioning effect for a Tumblar's body when they are rolling. It seems in it entirety, that Tumblars where simply born to roll down hills. Many have studied these gentle creatures for this very reason, since there are few uncivilized beings that specifically seek out play like they do.

Tumblars aren't hostile, but accidents have occurred, where people have been hit by Tumblars at high speeds. It just so happens that Tumblars aren't capable of stopping themselves once they've started rolling.

Due to their quite dangerous hobby, Tumblars are an endangered species and may therefore not be harmed deliberately. Although their bodies are designed to roll and tumble downhill, their protective fur only protects them to a certain extend.
