You can obtain Mario Kart World’s unlockables through various methods, so here's how to get new stickers, karts, characters, and costumes.

Stickers are strictly visual customization items serving as one of the main collectibles of Mario Kart World. They can be used to add a bit of flavor to your profile, karts, and scoreboard. Think of icons and player cards in modern Call of Duty titles, for example.

To unlock outfits in Mario Kart World, you’ll need to locate the various Yoshi restaurants while playing as the character you want to unlock costumes for. Eating at the restaurant will unlock a respective outfit for said character, with different foods leading to different outfits.
