Which Nintendo Switch game lets players control Mario with a sentient hat named Cappy?

Super Mario Odyssey is the Nintendo Switch game in which Mario partners with the sentient hat Cappy.

Cappy is a member of the Bonneter species and takes the form of Mario’s cap. By throwing Cappy, Mario can attack enemies, interact with objects, and capture certain creatures and characters. Capturing lets the player temporarily control their abilities, making the mechanic central to the game’s exploration and puzzle design.

Nintendo released Super Mario Odyssey on October 27, 2017. The 3D platformer follows Mario across a series of kingdoms while he tries to rescue Princess Peach from Bowser. The game also introduced the airship Odyssey, which carries Mario between destinations.

Cappy is not simply a cosmetic replacement for Mario’s normal hat. The character has a story role, a distinct visual identity, and gameplay functions. The game is therefore commonly remembered both for its globe-spanning kingdoms and for its capture mechanic.
