Theme tune to the WB cartoon:

We're tiny - We're toony
We're all a little loony
And in this cartoony we're invading your TV

We're comic dispensers
We crack up all the censors
On Tiny Toon Adventures get a dose of comedy

So here's Acme Acres - it's a whole wide world apart
Our home sweet home
It stands alone - a cartoon work of art

The scripts were rejected
Expect the unexpected
On Tiny Toon Adventures - it's about to start

They're furry - they're funny
They're Babs and Buster Bunny
Montana Max has money, Elmyra is a pain

Here's Hamton and Plucky
Dizzy Devil's yucky
Furrball's unlucky and Gogo is insane

At Acme Looniversity we earn our toon degree
The teaching staff's been getting laughs since 1933

We're tiny - we're toony
We're all a little loony
It's Tiny Toon Adventures - come and join the fun!

And now (my/our)* song is done

* To me, anyway, it distinctively sounds like Buster and Babs (who are singing almost all the theme) say respectively 'my' and 'our' at the end.
