Whimsical Song

View solution.
If only I had some blanks to fill in this text...
What a zany puzzle by a Bear named Pooh,
Who writes songs that are confusing through and
Piglet solved this puzzle, therefore so can you.

Turns out writing poems isn't all that hard.
Make up a few lines and you'll be called a bard.
But be sure they're rhyming, otherwise it's bad.

Better solve this puzzle before it's too late.
All your friends around you simply cannot wait.
If you fail to solve it, they will get irate.

Can you figure out the answer to this rhyme?
Find a hat, escape the woods, sign in on time?
I don't seem to have another rhyme for "rhyme".
