Animals I Want to Be

I want to be a puma,
A slippery, sliding shadow,
A clever, killer rumor.

I want to be a cricket,
A hidden music maker,
Master of the racket.

I want to be a hippo,
Sleeping underwater,
Chummy, chompy, chipper.

I want to be a possum,
Dying just for play,
A haunting, nightly problem.

I’m a typicalish human,
Lots of little things,
But big and broad and booming.

Which animal wants to be me?
