This stage is based off of the side-scrolling game Pac-Land released in 1984. In the game, Pac-Man is tasked with delivering a fairy to the Fairy Queen. He must run through levels to reach the door to Fairy Land and hand over the fairy. Once he does so, the Fairy Queen gives him a pair of flying boots which he can use to more easily return home.
The stage adaptation for Smash Bros. appears to be a recreation of the town level. Once you reach the end, you'll meet with the Fairy Queen, then make a return trip to the start of the stage before going through the level again during sunset.
