What each player can do here

P1 · Player 1
  • Mario, Luigi, Peach, Daisy or a Toad: grabs the power-ups, takes the hits, and can bring a fallen partner back by touching their ghost before it fades.
P2 · Player 2
  • Yoshi or Nabbit: no damage from enemies, but no power-ups either. A Yoshi can carry a partner on its back.

If your skill levels differ: Give the newer player Yoshi or Nabbit: Nintendo recommends them for players just starting out because enemies do not hurt them. The trade-off is that they never transform with power-ups. How to split the roles

The courses

Part 1 of 2. Clear the world and gather Wonder Seeds.

  1. BothBesides the regular courses there are badge challenges, a Wiggler race, a KO Arena and short Break Time! stages; the palace comes last.
  2. BothBulrush Express is the toughest regular course here, rated four stars in game.

Pipe-Rock Plateau Palace

Part 2 of 2. Beat Bowser Jr. for the Royal Seed.

  1. BothHe starts by spinning across the floor in his shell. Wait for the spin to end, then jump on him.
  2. BothAfter the first hit he shrinks you or himself: first you turn big and he turns small, then he grows huge and tries to ground-pound you.
  3. BothKeep waiting out each attack before you strike; three hits beat him and the Royal Seed appears.

Where people tend to fall

  • Going at him head-on is risky; wait for his attack to finish, then strike.
