What´s the meaning of Toodle-ee-oo kangaroo?

I have no idea. Where did you find it?

I'm prepared to take a stab in not-so-dark on this one.

In BrE, "toodle-oo" is a way of saying goodbye. I've never seen it with "ee" in the middle but it's close enough.

See ya later, alligator.
In a while, crocodile.

It seems to me that "Toodle-oo, kangaroo" might be a new addition to the list of rhyming goodbye phrases above.
