This ability is gained in the game as a permanent ability and allows you to possess most things in the game with few limitations. The main change to gameplay in this hack is the addition of Crappy from Super Mario Odyssey which grants players the ability to possess objects and enemies and use their unique abilities to their benefit.
Super Mario World Odyssey plays nearly identically to the original game and maintains its charm while aiming for interesting and challenging maps in the vein of SMWs award winning level design.
