There once was a caterpillar named, uh, "Caterpillar"...
He lived in a jar, not very far
from Preston's bed shaped like a car.
Then one day, Preston said "Hey!"
As he looked at his caterpillar gone brown.
I said "He's not dead, he's just sitting down with a big frown, so settle down."
But really, the caterpillar was toast,
too many days in a jar to roast,
with a 3 year old showing him to everyone to boast.
Goodbye caterpillar, it was fun.
While you were in a jar out of the sun,
Kept, admired, and loved by our little Preston.
