Rumbly in my Tumbly song
From "Winnie The Pooh and the Honey Tree"
Written by: Richard M. Sherman and Robert B. Sherman
Performed by: Sterling Holloway [Pooh]

Hum dum dee dum
Hum dum dee dum
I'm so rumbly in my tumbly
Time to munch an early luncheon

Hum dee dum dum

{hits head on branch}

Oh I wouldn't climb this tree, if a Pooh flew like a bee
But I wouldn't be a bear then, and so I guess I wouldn't care then
There's some honey and I'm a Pooh bear and that's all I do
  care and so I'll climb there

I'm so rumbly in my tumbly, time for something {smack's lips} 
time for something
{branch breaks}
sweet ... to eat
