The heroic rodent is inserted into the ancient Greek tale of Prometheus and Pandora. A little girl mouse is dancing in her yard. She has everything that she could want: ice cream trees, lollipop trees and a wishing well. The lowly fieldmouse is given a mysterious chest by Witch Hazel. The mysterious box is dropped from the sky with a note on it: "Do Not Open." She opens the box anyway, and a cluster of "bat cats" create mayhem. Oh, say... where is Mighty Mouse?
