I drew a model sheet of Mephie. Unfortunately, the 3DS camera doesn't work super well, so I'll describe them in case you can't see it well. (EDIT: I retook the photo in better lighting conditions. I think it helped a bit. )

Top:
-Mephie Stinktress(the "I"s are dotted with biohazard logos)
-Mephie with a confused expression
-Back view of Mephie farting

Bottom:
-Profile view; Mephie's wafting stink away
-3Q view; Mephie's making a greeting gesture
-Front view; Mephie points to the viewer, saying "Pull my finger."

And yes, I added definition to her butt. She's a skunk and she's always farting; it just made sense. X3
