Kirby 64: The Crystal Shards/Magman

Neo Star Boss
This boss is a giant blob of lava that you fight in a volcano.

Step 1: Magman will be in the background, so you attack the lava towers that he shoots at you. Be careful when dodgeing, because there is lava on the ceiling.

Step 2: Magman will try to corner you on the other side of the field. Attack his head to damage him until he falls. Don't be hasty or you'll waste a shot at him.

The best ability to use for this battle is double bomb, which is a tri-missile ability.
