Edd's Maze is a maze that Edd built in "They Call Him Mr. Ed". Edd refers to it as his "Maze of Inevitable Despair." He built it for an experiment involving Ed, where he presumably wanted Ed to find his way through the maze using nothing but his sense of smell. As incentive and a prize, Edd set up a complete breakfast at the end that included delicious Chunky Puffs. Unfortunately for Edd's plans, Ed didn't go through the maze in a typical way, instead choosing to run straight through the cardboard walls of the maze, wrecking it. Ed's haphazard route through the maze annoyed Edd, but he soon forgot about it when Eddy arrived, beckoning the two on to another project.
