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.

One of the most popular arcade games of all time, PAC-MAN's phenomenal success in the 1980s led to it becoming one of the defining characters of the decade, and an icon of popular culture. Hugely influential, the original arcade game was first released in Japan in 1980, and soon changed the face of the entire computer gaming industry. Even modern day blockbuster gaming franchises such as Metal Gear Solid and Grand Theft Auto can trace their origins back to this cute little pizza shaped trail blazer.

This clever PAC-MAN Heat Change Mug design shows the classic character in full flow, munching his way through the maze while avoiding his ghostly enemies. So get the kettle on and recharge your energy levels with a little help from a bona fide gaming legend.
