Super Mario Bros. Wonderland 1987

Blue Bowser (Bowser's brother who only appears in the Lost Levels) is making a big mess in the Flower Kingdom. He wants to be as mean as Bowser having a kingdom just for him. Next to the big villain is Blue Bowser Jr. his son and together they try to stop the Mario Brothers from proceeding. The fan game contains secret worlds if you collect all the Wonder Seeds in all the worlds.

Résumé

Super Mario Bros. Wonderland 1987 (also known as Wonderland 87), is a fan game that portrays Super Mario Bros. Wonder in a different way. It's as if the game was released around 1987 after SMB Lost Levels and before Super Mario Bros. 3. The story is completely different from the original game.
