In need of a power-up boost? Then why not turn to the little guy who originally invented the concept in the first place, with this retro-cool Pac-Man Heat Change Mug. When cold, this stoneware mug shows an empty Pac-Man maze, but once a hot drink is added, the maze fills with all the characters from the classic game, including the legendary ghosts Blinky, Pinky, Inky, and Clyde, plus of course the round headed hero himself. Hand wash only. Not dishwasher safe. Do not microwave.
