Puddle Prison Puzzle

I can’t leave this puddle.
Ever since it rained
No matter how I struggle
I’ve been stuck in muck befuddled.

This puddle prison puzzle
Has got me awful ruffled.
The toughest type of trouble
Is muzzlingly subtle.

Interesting though…
Not to get too sappy,
This cold and wet seems… happy.

I think…
I think…
I’m mud!
I am this muddy muddle!
I don’t want to leave this puddle.
