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)

Redonkulousaurus 

Redonkulousaurus is an extension of the word "redonkulous," (popularized by the O.C.'s Seth Cohen) and serves to hyperbolize the already-supercharged fictional word. It was first used by Yula to describe her massive textbooks. Redonkulousaurus can be used as both a noun and adjective to describe something so utterly absurd, that it goes beyond the span of human imagination.

She has, like, $300 in her wallet. That's redonkulous.

Your mom is a friggin' REDONKULOUSAURUS. How many pizzas does she eat a day?

That textbook is REDONKULOUSAURUS.
