Catch a Little Rhyme

Once upon a time
I caught a little rhyme

I set it on the floor
but it ran right out the door

I chased it on my bicycle
but it melted to an icicle

I scooped it up in my hat
but it turned into a cat

I caught it by the tail
but it stretched into a whale

I followed it in a boat
but it changed into a goat

When I fed it tin and paper
it became a tall skyscraper

Then it grew into a kite
and flew far out of sight...
