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!

momasaurus 

over protective, yet micro-managing mother who uses guilt to try and make you change your mind

Everytime I try to explain to my momasaurus my future plans she gets upset and then tries to discuss how if I do it a different way my life would be easier.

Mika (Mikasaurus) 

The most amazing non-professional singer in the entire universe. He is also the last remaining Mikasaurus in the entire world. He's really nice and funny and awesome at everything. He will completely deny these facts because he's too modest. He's amazing and I love him. (:

"Where is Mika (mikasaurus)?"
'Off being amazing."

Mamasaurus

Similar to a Mama Bear, the Mamasaurus will protect her little dinosaur in every way that she can. This can be anything from burning your hand on the stove to defending you from a bully at school. Mamasaurus has got your back!

You better leave me alone or my Mamasaurus is going to get you!
