mermasaurus rex

A mermasaurus rex is a mythical creature designed by 2 of the earth's most intelligent minds, Blake and Angela. It is half mermaid and half t-rex. the upper half is that of a beastly tyranosaurus rex and the lower half is a mermaid tail. The mermasaurus lives alone on remote islands around the world usually laying out in the sun, listening to boy George, doing the crossword puzzles in the New York times, chain smoking and swearing like a sailor. They can only be seen by those with an open mind or children. If you happen to be one of the lucky few who get to meet one you will likely receive a golden coin with an image of boy George on it from them. Be polite and don't act afraid or they will eat you in one bite.

The mermasaurus rex loves to sunbathe on the island.
