What's choohoon or to choohoo? (The spelling may be way off.)?

Question

In an old black and white cartoon, a little girl is singing to Santa Claus telling him what she wants for christomas. The song goes:

I want a drum, a tinny cup,
a hobbyhorse, the lollipop,
A little *choohoon* that I can *choohoo* will make me happy.

At least this is what it sounds like, and the last line baffles me. Can someone help?

Answer 1

A "choo-choo" is a child's term for a train, and it's also a child's term for the sound a train makes. It could refer, in this case, to a toy train.

Answer 2
