One day, I somehow ended up with the song “The wheels on the bus” stuck in my head, and I somehow started coming up with my own lyrics for it. Here’s an example:
The Penguin waddled back and forth, back and forth, back and forth. The penguin waddled back and forth, all through the town.
Then goes on to the next lyrics. The form is
The | (two syllable animal name) | (verb) – ing | (three syllable description)
Examples:
The rabbit hopping up and down
the lizard scampered all around
the panda sitting on the ground
the giraffe standing tall and straight
the hedgehog hiding in a ball

You can easily add more lyrics. This could be a fun song to play with kids, and when they sing the verse they act out what the animal is doing (hopping for the rabbit, sitting for the panda, etc.)
