Mario's greedy doppelganger, Wario, stole Mario's castle while the hero was off rescuing Princess Daisy in Sarasaland. Mario has to collect six golden coins to open the gates and eject the unwelcome houseguest.
This game marked Wario's first appearance, and it was also much more in line with new Mario games like Super Mario World than the first Super Mario Land: it included floating rabbit ears and map screens.
