"Woooo HOO! Simply splendid! I'm awash in delight! I must tell you a smidgen about the pachycephalosaur! This unique creature was one of the last dinosaurs to roam the earth, wot? Though it is known primarily for its rounded head... It was basically all bone! There was hardly a brain to speak of inside! These brain-boggling dinos never cease to amaze me! Hoo, so intriguing! Ah. My my! Terribly sorry. I babble... You must wonder if I've a brain in MY head!"

In City Folk
"...Hoo my! At long last, the pachycephalosaurus is complete! Hootie woo! The wonder of it all! Pachycephalosaurus roamed the earth right up until the end of the dinosaurs, wot? Its characteristic round skull boasted bone that was almost a foot thick... Quite thick indeed! But its head wasn't especially big...so it had little room for any brain..."

''"The pachycephalosaurus is known for its round, helmetlike head, the use of which is still debated. The bony dome atop its skull was nearly a foot thick, which is why mostly skull fossils survive. Some theories say the animals would smash their heads together to determine pecking order."
