This is a mashup of the classic Tiki Bob mug by Alec Yuill-Thornton with the Creature From The Black Lagoon. This Bob has green skin except for his face which is white with black details.

From TikiLand Trading Company:

"Once thought to be a dangerous otherworldly being, this creature is now known by the world by his great smile, and where this gill-man resides - the black lagoon, deep inside the Amazonian jungle. Enjoy your grog with Creature Bob while at a tiki bar, home bar, or while watching an old black & white. This ceramic tiki mug is about 7.5 inches tall, and holds about 26oz!
