Tostarenan

Tostarenans are sentient skeletal-like creature from Tostarena within the Sand Kingdom in Super Mario Odyssey. They are usually seen to be dressed in traditional Mexican clothings like sombreros and ponchos, and are often seen playing maracas or guitars. Despite their skeletal appearance, Tostarenans are not dead since Chinchos are undead blue Tostarenans and acts as mindless hostile creatures unlike the living Tostarenans who are friendly toward Mario.

The Tostarenans also run a slot game that can be played to win coins, Life-Up Hearts, and Power Moons. These Tostarenan-ran slot games can be found in the Sand Kingdom but also in the Metro Kingdom and in the Luncheon Kingdom. At the game's finale, in the Moon Kingdom, a few Tostarenans can be found in attendance of the wedding between Bowser and Princess Peach. They comment on how they were brought forcefully by Bowser. After that, Tostarenans will be found in most other kingdoms where they acts as tourists.
