Part 16

Gold Dragon Head: This is the hardest fight. Start as Mouse, jump left towards the wall, and wait for the head to approach. Jump over it and stay near its chin to place bombs. When it flies into the air, stay in the middle of the screen as Mouse and jump over the energy balls. As the last balls are fired, it will land; quickly get to its chin and bomb it again before it takes off. Mouse does the most damage, but Lickle or Dragon can be used if necessary.

Floating Castle 1: Start as Golem. Punch the bouncing eyeball, then the flaming skull above you. Kill another eyeball and skull, then punch the skull on the ground. Walk right to the wall, jump up the three ledges, and punch the slug. Pick up the health increase on the right. Jump to the platform on the left, walk right to find a large heart, then jump up and kill the slug on the ceiling. Head right on the next ledge, kill the slug, go left on the next ledge, find a large heart and another slug, then kill it. Jump right to the next ledge for another health increase. Kill the slug above you, then jump up the ledges on the left. Switch to Lickle and climb the wall on the left to the ceiling. Climb right across the ceiling to avoid enemies below. Drop to the floor when you can't go further and head right off the screen.

Grim Reaper II: This boss fight is similar to the first encounter. The Grim Reaper II summons two ghosts that replace each other when killed. It moves in a circle in the air, then teleports. Keep moving to avoid its attacks. The main difference from the first fight is the absence of an elevated platform in the middle of the arena, which may make this fight easier.

Green Cyclops II: This boss can shoot consecutive curved fireballs and a homing energy ball that splits into two smaller homing balls if destroyed.
