From 'Jeff's Secret'. Clarence is watching a documentary about animals and he starts daydreaming Jeff as all the animals while this music plays. It's a pastiche of Tiptoe Through The Tulips by Tiny Tim.

LYRICS

As I bumble
In the jungle
and I mingle
With the friends I see
What a merryment making my menagerie
Hee hee hee hee hee hee

As I bumble
In the jungle
There’s nowhere else I would rather be
I’m a merry old melon
With my menagerie
Hee hee hee hee hee hee

Bumble In The Jungle [For Cartoon Network's Clarence]
