emosaurus 

The Emosaurus is a large orange dinosaur, with razor sharp metallic teeth. The Emosaurus spends its time roaming the world looking for Emo kids to eat for breakfast.

With its keen sense of smell, and ultra-sensitive Emo-detection hearing, It is quickly attracted to the smell of slitted wrists, and the sound of Simple Plan music.

The best way to avoid the Emosaurus is too stop living in the "Black Abyss." If you enjoy simple plan music, keep it low so that the Emosaurus understands you are not trying to make everyone else suffer.

-The Emosaurus ate the Emo kid for breakfast
-The Emosaurus makes the world a better place
-Go play with the Emosaur

Morosaurus

A semi aquatic monster/dinosaur that comes out and beats kids with anything available. If it be a pole or a canoe paddle, no one is safe. A morosaurus is very protective of his turf and will defend it at any cost. If you ever run across a morosaurus, the only way to escape is to yell "You won't" or "Square Up" as loud as you can. He will see it as a very offensive act and will scurry off into the wilderness.

That creature looked alot like a morosaurus!

Mansaurus 

A comprehensive tome of reference and learning on how to be manly. For some, manliness doesn't always come naturally, and the Mansaurus is an essential guide on how to behave in a manly fashion, use manly words spoken in a deep manly voice, and use one's body language to show how manly one is. Many famous manly celebrities allegedly have a copy tucked away including Chuck Norris, Daniel Craig, Russell Crowe, Madonna, Pink, and Fergie from the Black Eyed Peas.
