Muriel the Musquash, a very good swimmer

Often thought she'd like to be quite a lot slimmer.

Though aquatic rodents shouldn't really be teeny

Instead of a one-piece she could wear a bikini -

A musquash bikini, next best thing to mink

Which would catch every eye on her way to the drink.

What she didn't consider was that, looking a peach

She was sure to be ogled by the rats on the beach.
