Little Bunny Foo Foo,
Hopping through the forest
Scooping up the field mice
And boppin’ ‘em on the head

Down came the good fairy and she said

“Little Bunny Foo Foo,
I don’t want to see you
Scooping up the field mice
And boppin’ ‘em on the head.
I’ll give you three chances,
And if you don’t behave
I’ll turn you into a goon!”
