Ninjapotamus 

A ninjapotamus is half ninja & half hippo creature that lives in a triangular shaped Umi Sake house. He eats bananas and drinks Jaeger bombs. He fights crime on the streets of Seattle pulling all sorts of kung-fu moves. It should be noted that his kung-fu moves arnt all that smooth. That's the key to the ninjapotamus. Hes very clumsy but he thinks hes very slick.

Is it a bird?
Is it a plane?
NO! ITS A NINJAPOTAMUS!
