Thanks,I'm not that fast. Gallade and the other guy got to world 6 before I did and I wont know if any modes unlock until I beat this world and I'm not finishing till I get these last two stickers. I'll let you know what happens after.
I am still at Area 3 and I found 0 Cubes in 1 of the stages, I must be blind hahaha, need to keep looking
