Sprixies are fairy-like creatures that first appeared in Super Mario 3D World. They are the native residents to the Sprixie Kingdom, ruled by the seven Sprixie Princesses. The name Sprixie is a portmanteau of "sprite" and "pixie," which are considered synonymous with "fairy." They bear some resemblance to the Subcons from Yume Kōjō: Doki Doki Panic/Super Mario Bros. 2, as well as Jojora from Mario & Luigi: Superstar Saga.
Sprixies appear in various levels and areas of each world, providing assistance to Mario and co. throughout the game. In certain areas, some appear with a pair of binoculars which (when viewed) shows the direction of the Goal Pole, similar to Binoculars in Super Mario 3D Land.
They also own and host the stamp-providing Sprixie Houses, the Mystery Houses, and the Lucky Houses.
- The green one, who is playable in Mario Tennis: Ultra Smash, is called "Sprixie Princess" in the game.
- Their homeworld and gender ratio are unknown.
