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
