[Intro]
Bum-bum-dum-bum bum!

Bum-bum-bum-bum intro-intro!
Bum-bum-bum a-intro-intro!

[Chorus]
It's the theme of Groose
Now the Groose is loose
It's the theme, yes, it's the theme of Groose

Hey, look, there goes Groose
Gonna buy some juice
Does anyone realize Groose rhymes with goose?
(Like if you did!)

[Verse 1]
It's Groose
He's drinking juice
Yes, it's Groose
Not a moose
(I can see the confusion!)

It's Groose
Riding a caboose
Wait, wrong game!
Hey! Come back with the train
(I need to pay it off!)
[Chorus]
It's the theme of Groose
Filthy, train-stealing Groose
How'd he do that, anyway? Uh, snoose

Snoose is a word, says Groose
Dictionary-less Groose
Throw the book at the train-stealing crook
Groose

[Verse 2]
It's Groose
He's now in jail
With a whale
He's on its tail
(Epic fail!)

Wait, Groose
What are you doing?
He used the tail as a spring
Now he's free
(Oh crap, Groose is loose!)

[Outro]
It's the theme of Groose
(No, no, don't you restart the song on me!)
Now the Groose is loose
(We aren't looping this!)
It's the theme, yes, it's the theme of Groose
(You still need to pay for stealing my train, Groose!
Come back here, Groose!)
