Never

...give your frog a boat

He won't know how to make it float

He'd stare at it with froggy eyes

Then trade it for a bag of flies

Never give your mouse a car

He'll leave the driver's door ajar

'Til all his mousy friends and kin

Bring all their kids and move right in

Never give your bird a plane

The neighbors surely would complain

When, instead of tweets at four

They're wakened by a startling roar

And never, ever, for the world

Give your pig a string of pearls

For piggy pigs won't just make do

She'll want a set of earrings too
