The first five "mousie marks" I've made for My Little Mousie characters. Clockwise from top, they belong to:
Squeaky-Pie,
Spazzy-Boom,
Riverbiscuit,
Conk-Out, and
Peanut Flutter.
"Mousie mark" is actually a placeholder term blatantly based off "cutie mark". The same goes for "My Little Mousie". Since My Little Mousie is a general parody mostly derived from both My Little Pony, Care Bears, and related, I really should come up with something a bit more mine, but beats me what it would be. :/
