The Monster Kids Jiggle and Wiggle both sing the song A cat came fiddling out of a barn together along with Mommy Monster, Daddy Monster and their sister Baby Monster.
A cat came fiddling out of a barn,
With a pair of bagpipes under her arm.
She could sing nothing but fiddle dee dee,
The mouse has married the bumble bee.
Pipe, cat, dance, mouse,
We'll having a wedding at our good house.
