These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Kirby's Dream Land
Alas, Poor Villain: He doesn't die, but it's hard not to feel bad for Dedede when you beat him Extra Mode and he slowly walks away crying.
That One Boss: Kracko in Extra mode. He moves very fast, giving you next to no time to react. Instead of throwing Waddle Doos, he now throws bombs. This boss battle is more about luck than anything else.
Though there is a way to make him the easiest boss in the game. If you stand in the left corner, you only have to worry about him charging at you and inhaling his bombs. The beam attack cannot hit you.
Kabula's shots spiral erratically, making it hard to dodge them, to the point that fights with her can easily just turn into a battle of attrition (especially in Extra Mode.)
