To take advantage of her absence, Koopa creates a Robot Princess who wrecks havoc on the Kingdom and tells the Mario Brothers that she has decided to name Koopa the ruler. // King Koopa and Kooky Von Koopa travel back in time to prevent the Mario Brothers from discovering the Real World Brooklyn Warp Zone that first led them to the Mushroom Kingdom! Toad and the Mario Brothers manage to stow away on the Doom Ship in order to thwart Koopa's History-making evil plan, only to be transported back too far in time and transformed into diaper-clad toddlers moustaches and all!
