Pac-Man: 1x14

Sir Chomp-A-Lot

Mezmeron creates a time machine in order to send the Ghost Monsters back in time 50 years before the Power Forest was hidden. But Inky’s blundering causes them to wind up in medieval Pac-Land where they’re confronted by Sir Chomp-A-Lot, brave Pac-Knight of the Round Table and Pac-Man’s direct ancestor.
