Kill Metal Pit on Classic mode without injuring him once!
Heres a hint which I found as I was getting up to Master and Crazy hands.
Ok I'll give this to you in these 5 steps
1. Select Kirby or any character that throws players to the side (I'd recommend Kirby since he can easily inhale)
2. Keep doing Classic Mode till you get Metal Pit
3. Inhale Metal Pit (grab him with other players)
4. Make Kirby go to the edge and spit him out off the edge (with other players throw him)
5. His wings won't help much cause of his metal weight, they acutally drag him lower!
