Kirby's Adventure (Virtual Console) Cheats (Nintendo Wii)

In Rainbow Resort, level 2, jump or fly up to the ledge above the entrance door. Stand
directly over the door, then fly up. You will enter a secret, hidden door. You skip the
first three mini-bosses, and after beating the last one (fireball lion), you will enter a
secret room with five 1-ups. Enter the door to your right to end the level.
