I'm still stuck on extra mode o__o.
It took me awhile to get past the boss of White Wafers(Go Fighter ability!) Plus I lost the game for like 4 months! Whenever my best friend and I want something new (not Kirby's Epic Yarn,we play that WAY too much!) we play Return to Dreamland. She plays as Meta Knight while I play as Kirby. (I'm a bit more skilled at the game)
