Whispy Woods is harder, but not by much. He will exhale
puffs of "spit" at your flippers, and Gordos and apples will
fall occasionally. Not too hard since Wispy is so big.
Poppy Brothers
In this fight, there are two platforms... and a Poppy
Brother. He will bounce around from platform to platform
occasionally throwing bombs which will stun your flipper(s).
After hitting him a few time, he will split and another
Poppy Brother will join the fight. They will keep throwing
their bombs, but as long as you keep hitting them, their
shots will become less.
Kracko
Things get harder here still, but also not as much. Kracko
starts off just as an eye, then evolves into a cloud. Kracko
will shoot off various things at you, beams and babuts
mostly. Still not as hard, but at one point he can be
invulnerable to attacks, causing Kirby to bounce around a
loose a little control.
King Dedede
When you rocket up to King Dedede, all you will see is
Kirby, the flippers, and King Dedede in a spotlight. He will
throw a few bombs, but hitting him back will cause all the
lights to go on, and he will start his Kirby "mock" of
puffing himself up and floating around. After hitting him a
few more times, he will become normal and start firing beams
with both hands at both flippers. Hitting him while he is
doing this will stop the him from firing the beams, and the
flippers won't even be stunned and go back to normal. After
beating King Dedede you have beaten game.
