From Mondo:

"Gurgling up from the depths to bring you a horrifying vessel from which to gulp your sinister spirits from, it's the official Universal Monsters Creature from the Black Lagoon Tiki Mug! This monstrous mug is designed by the deadly Doug P'Gosh, sculpted by the mischievous Matthew Black, and produced with the help of the terrifying Tiki Farm team. Creature features his horrible visage on one side, a scream scene from the film on the other, and holds 16oz of the lethal liquid of your choice! The only thing fishy about this mug would be not adding it to your collection!

This version of The Creature features a yellow base blaze, with a Gillman Green wiped glaze over it."

The first edition in green with yellow base is a bit less vivid and has a matte finish. This new version has a satin finish and is more vivid/brighter with more yellow popping through.

This was part of the re-launch of a select group of previously issued tiki mug designs by Mondo after its buy-out by Funko.
