Topic: Who managed to get the checklist done in Kirby Mass Attack?

I can't get all the gold medals because of that one boss rush mode that frustrates the hell out of me. Its this reason AND this reason alone that I don't ever want any achievements in not only kirby games but also on any Nintendo games in general.

Granted its optional but my god that Boss level!!!!!!! :<

I've got all but two of them; the game says I'm 98% complete, lol.
