The Field Guide is where players can look to find the items they found during quests (finds), bits they own or have owned (stuff), powerups they have the ability to craft (powerups), gadgets they have crafted (Gadgets), and Kart Parts they own (Kart Parts).

It can be accessed from the Craft It Booth or while crafting anything from the crafting menu on top of the screen.

It is the only piece of evidence we have of the names of the Quest Worlds.
