A tiny dinosaur that likes to pretend he is a turtle. His shell is really an acorn. He has his own comics and is usually wondering why humans do something like eating lots of noodles when he can only eat one because he's so tiny.
Holly: Did you see that new comic?

Jane: Yeah! Sheldon the Tiny Dinosaur is so cuteeee!

Holly: It's so awesome!
