Rolling Over the Billows, Down by the Bay, Second Story Window, and Jenny Jenkins come to mind. and now that we're selling rhythm frogs in my shop, the Froggy song keeps popping into my head too.

Dog! Dog, cat! Dog, cat, mouse! FROGGY! Itty bitty teeny weeny little bitty froggy Jump, jump, jump, little froggy See the little froggy coming to the highway Ribbit, ribbit, ribbit, ribbit, Croak.

(Or, if you perfer a bloodless version,

See the little froggy coming to the lilypad Ribbit, ribbit, ribbit, ribbit, Splash.)

And

Oh, isn't it a piece of luck that i was born a baby duck With yellow socks and yellow shoes that i may go wherever i choose!
