This easter egg is located inside Endon's house in Markarth.
Located inside Endon’s Markarth house there is an arrangement of items made to look like Pac-Man eating pac-dots.
Once inside the house walk up a small ramp to your left and look to the bottom row of the bookshelf on the left wall to see the easter egg.
• A Cheese Wheel for Pac-Man’s body
• A Slaughterfish Egg for his eye
• 3 pieces of Garlic for the pac-dots
• A Bowl of Glowdust to represent a power pellet (it’s also been stated that the glowdust may represent one of Pac-Man’s ghostly enemies since players in Skyrim are required to “kill” wisps (ghosts) in order to obtain it.
