We'll start here if you don't mind
The shortest word that you can find
Add a letter right on the end,
A preposition is your best friend.
Add another to get a creature,
Sensitive ears are his best feature.
Add one more and have a thought,
You'll find out what the Go-Go's got.
Why stop now, we'll go again,
Try to find Beauty's friend.
Once more - the word's no longer teeny,
A natural support for a bikini.
One more letter for a final twirl,
no clue at all ('cept that it ain't plural).
