How about "If I Were a Moose" by Fred Small. It's an allegory based on a true story, about a bull moose who really did come a-courtin' a cow, in New England somewhere, I think.

"If I were a moose and you were a cow
Would you love me anyhow?
Would you introduce me to your folks?
Would you tell your friends 'No moose jokes!'"

Or there's another one by Fred based on a different true story-"Hot Frogs on the Loose", about frogs that were exposed to radioactive stuff at a nuclear power plant. It's great with kids, cause there are different noisy parts for the audience to do, such as the frogs going "Gurk, gurk" and the frightened populace screaming.
