Thud! Thud! Pachycephalosaurus

"What is that sound?"
"Uh?"
Bump bump bump
We are the kings of head-butting
Pachycephalosaurus
A dreadful head of stone
Thud thud thud
Bump our heads
Let's pick the Strongest
Bump bump bump
A thick hard skull
Great stubby bumps
A pointy pointy beak
Stretched out the heavy tail

"Roar!"

Thud thud thud I am the best
"The fruit is mine!"
"I found it first!"
"Well, Bring it on!"
Bump bump bump
We are the kings of head-butting
Pachycephalosaurus
A dreadful head of stone
Thud thud thud
Bump our heads
Let's pick the strongest
Thud thud thud
Put your head down
Run fast! Hard! Go
Take it, Super Head butt time
Thud, Thud, Thud,
Thud,Thud,Thud, Thud,Thud
Thud Thud Thud
I am the best
"Do you want to fight?"
"Ah! Run away!"
