The Greedent character who teaches cooking in Pokémon Pokopia is Chef Dente.
Chef Dente is one of the named Pokémon encountered as the player restores habitats. The character is a Greedent who previously belonged to a chef trainer, giving the cooking role a direct connection to its backstory.
Cooking is one of Pokopia's everyday life-simulation activities. Food can be prepared for Pokémon or for Ditto, and the game's cooking systems add another way to care for characters outside building and exploration.
The name is easy to confuse with the species name Greedent. Greedent identifies the Pokémon species, while Chef Dente is the individual character's nickname. Pokopia uses several similarly styled special names, including Peakychu, Smearguru, Mosslax, and Tinkmaster, so the character name matters for a precise answer.
