Pachycephalosaurus

There’s a pachycephalosaurus lying on the floor
cos the pachycephalosaurus banged his head on my door.

He didn’t know who lived there
He thought he’d better knock
He didn’t know the door was made of solid rock
So there’s a pachycephalosaurus …..

If he charged a dinosaur he could knock it down
Because he’s got the hardest head of anyone around
That pachy’s head is very hard, his skull is very thick
But his head’s not hard enough to bang against a brick

So there’s a pachycephalosaurus …..
