Write a song for children that starts with 5 spring-related animals and counts downward to none, similar to "Five Little Pumpkins." 
Five little ducklings were swimming in a pool,
The first one left when he felt a little cool.
The second one ran when she got splooshed,
The third one split when a big wind whooshed.
The fourth one went to pick some pretty flowers,
And the fifth one cried, "We've been here for hours!"
The pool was empty until the next day
When the five little ducklings waddled back to play!
