The shark lady PlayerModel and Ragoll is made by Steam's Lenoax and this screenshot's taken from Valve's Garry's Mod.

She was enjoying going to the Fish and Chips shop and just enjoyed plenty of cooked fish, potato cakes, chips and who knows what else and has indeed stuffed her face silly enough to unleash the beast out of her giant belly. She seems to be in a happy mood to wink at you guys and hope you may give her more fish and give her belly lots of drums and kisses, if you like to.
