What each player can do here

P1 · Player 1
  • Mario, Luigi or a Toad: the standard heroes, who get the full effect of every power-up, including the gliding Super Acorn.
  • Toadette can take this seat too: the Super Crown turns her into Peachette, who floats, double-jumps and bounces back once out of a pit before landing again.
P2 · Players 2–4
  • Nabbit: enemy attacks never hurt him and his courses start with 100 extra seconds, but power-ups do nothing for him, and pits, lava, poison or getting crushed still cost a life.
  • Either player can tuck into a bubble during multiplayer and float along until ready to rejoin; Deluxe uses two buttons held together for this.one guide

If your skill levels differ: Nintendo made Nabbit and Toadette for younger and less experienced players, so the newer player takes one of them. Nabbit ignores enemy hits, which means that seat mostly fails on pits and lava; the more confident player takes Mario, Luigi or a Toad and grabs the power-ups. How to split the roles

The courses

Part 1 of 3. Clear the world's nine courses.

  1. BothNine courses: five regular ones, a ghost house, a secret course, the tower and Wendy's castle.
  2. BothThis world is optional: a run that takes Sparkling Waters after the desert can skip it.
  3. BothA Bubble Baby Yoshi can be picked up on this world's map.
  4. BothClearing Wendy's castle also opens The Mighty Cannonship.

Freezing-Rain Tower

Part 2 of 3. Outclimb the rising platform and beat Boom Boom.

  1. BothIcicles hang from the ceilings along the climb. Late in the tower a platform rises steadily; wall-jump to stay ahead of it and watch for icicle rows above.

Wendy's Shifting Castle

Part 3 of 3. Get past the Thwomps and beat Wendy.

  1. BothThwomps line the route; let each one drop and rise before you pass under it.

Boss

Boom BoomThe tower boss

  1. On ice: He jumps and keeps his spin as in the last tower, and this time the arena floor is ice.

Wendy O. KoopaThe castle boss

  1. Rings and icicles: Wendy skates across the ice and fires rings that shake icicles loose from the ceiling. Hit her before the icicles come down; three stomps beat her.
