I figured I get this thing started with a classic. Bid by comment below if you'd like to take a place on the link set. Warning: You WILL get slimed. Bidding will close Sunday, March 9 at Midnight Central U.S. time.

What the winner will get to choose:
Character, obviously (I typically draw female, and anticipate better results that way, but you can have what you want)
Outfit (or not, if that's your preference)
Reaction to the slop
If you wish, you can flesh out the situation with additional script. Perhaps additional mess if I like what you're going for

What you get (guaranteed):
One clean pic and one slimed pic in something like the pose shown
Whatever else I feel will effectively depict the scene you want
