Fugu is a puffer fish-shaped mug manufactured by Munktiki. The fish is in full-puff mode with bulging eyes, puffy lips and several wide spines sticking out of his body. This version was issued on Saturday July 18 2015 from 6 AM to 10 PM as part of the random "Day of Gold" where different gold glazed versions of Munktiki designs were made available throughout the day -- similar to the Black Friday event hosted previously.
