Fugu is a puffer fish shaped mug manufactured by Muntiki in many different colors and finishes. The fish is in full puff-mode with bulging eyes, puffy lips and several wide spines sticking out from his body. The older versions had two additional holes on top for straws. This version uses a "crawl" glaze effect where the top glaze coat separates like alligator skin to show a glaze beneath with an organic effect. In this case, the tan overglaze separates to show black beneath.
