Redonculosaurus
This prehistoric, newly discovered species resembles a wet koala mixed with a dodo bird. Do not be fooled, though, if you give the Redonculosaurus any facts about US presidents, it will implode the universe on queue. The Redonculosaurus was found out to be highly dangerous, as it traveled at over a million miles per hour and could detonate anything it came across with one foul swoop.
"That Redonculosaurus was the one that destroyed my home!" (As translated from ancient cave wall writings)
