This is a mug shaped like a poisoned apple (a la Snow White and the Seven Dwarfs) with a Tiki Bob style face that has a crossed-out eye and stitches on the mouth.
From Lost Temple Traders:
"One taste of the Poisoned Bob and the victim’s night will change for better. Cheers to all the bad apples."
There is a green First Edition of this design as well as a blue "Moonlight" Second Edition
