You are a crab,

Ready to snap someone.

You are the number 8,

slithering like a slithery snake.

You are a green pen,

ready to cross out writing.

You are a naughty murderer,

ready to stab someone.

You are a curious child,

answering everything that he you can do

You are a brain,

powering like a light bulb.

You are a normal person,

splitting in 2 to form the number 10.

You are the chaser,

trying to beat contestants from answering questions.
