I'm going to unlock all characters, their star versions, stadiums, minigames, error items, and badges in this walkthrough. I'll be going for the characters and items first, then will do the minigames last.
In this part, I face the Yoshi Eggs on the All-Star difficulty. I get my revenge against them this time around.
