Belly Button Frog

There's a frog that lives in my belly button; he only comes out at night. First time I heard a little croak, he gave me quite a fright. I looked behind the cupboard and checked under the bed, Then a little tickle made me peek beneath my shirt instead.

Every kid wants a pet, but to wake up and find a frog living in your bellybutton ... Mum warned me to use soap.
