Mother Goose Rhymes by The Riddler (pt. 5)

The bat came flying from his cave,
Many civilians he must save.
Two-Face, Joker, Ivy, and I—
Very quickly must he fly.

Original:

A cat came fiddling out of a barn,
With a pair of bagpipes under her arm;
She could sing nothing but fiddle cum fee,
The mouse has married the bumblebee.
