T-rex Mystery Box

"Look at those presents!"
"Let's open them."
What special present is
Hiding in the present box?
Boom, boom, boom, boom, boom
Maybe it's a crayon set
I'm a red T-rex
Popping out the present box
I'm a cool T-rex
Hiding in the present box
"I hope mine is a toy."
What special present is
Hiding in the present box?
Boom, boom, boom, boom, boom
Maybe it's a toy car
I'm a blue T-rex
Popping out the present box
I'm a cool T-rex
Hiding in the present box
"Let's open ours too!"
"I wonder what's inside!"
What special presents are
Hiding in our present box?
Boom, boom, boom, boom, boom
Is it a robot or a doll?
We're yellow and green T-rex
Popping out the present box
We are cool T-rexes
Hiding in the present box
"Don't run away! Let's play!"
