Five Cranky Crabs

Five cranky crabs were swimming in the shore.
One swam into a net and now there are four.
Four cranky crabs were floating off to sea.
One got tangled up in seaweed and now there are three.
Three cranky crabs were wondering what to do.
One dug a deep hole and now there are two.
Two cranky crabs were warming in the sun.
One got scooped up in a cup and now there was one.
One cranky crab was smarter than his friends.
He hid between the jagged rocks and that's how it ends.
