cockopotamus
A cockopotamus was the result of a science experiment gone wrong in 1776. The experiment created a new species called the "cockopotamus" which is a mix breed between a penis and a hippopotamus resulting in the shape, size, and color of a human penis, with the size of an entire hippopotamus.
