I also wanted to share a funny story. A few weeks ago I went shopping with my wife. We went to Sams Club here in Mexico and bought "Choco Krispies" I believe you know it as "Cocoa Krispies". Well the back of the cereal box which often has stuff for little kids had this:
Chocokalibur! wow that was interesting and I decided to keep the box and later do a makeover of this map with my own lore and ideas. But I thought it was very interesting to see a dungeon on the back of the cereal box.
