What each player can do here

P1 · Kirby
  • Kirby: the adventure is Kirby's; the other players join around Kirby as another Kirby or one of Kirby's friends.
P2 · Players 2–4
  • Players 2 to 4 can join at any point as King Dedede, Meta Knight, Bandana Waddle Dee, or a Kirby in another colour. Joining costs a 1-Up, but it still works with no lives left (that player starts with half health).
  • Ride piggyback on another player, then press and release L or R together for a Team Attack.
  • A Super Ability swung at another player only knocks them back; it never hurts them.

If your skill levels differ: If anyone is new, turn on Helper Magolor: everyone gets a potion that doubles maximum health, and Magolor pulls players out of bottomless pits. Riding piggyback on another player also lets the two of you combine into a Team Attack. How to split the roles

The stages

Part 1 of 2. Clear the stages and collect the Energy Spheres.

  2. BothWhen it puffs up it is about to roll or charge at you; get into the air to let it pass.
  3. BothIt also leaps and slams down; jump clear of the landing.
  4. BothAt half health it inflates to fill almost the whole arena. Do not get pinned against a wall when it charges.
  5. BothIn the second half it fires a huge stream of water along the floor (jump over it) and stomps to bring down stalactites (stay out from under them).

Where people tend to fall

  • TheGamer: the safest times to hit it are while it inhales and just after it deflates.
