 There are three NPCs you must trade with in Pokémon Scarlet and Violet. The first one is in Cortondo and he wants a Flabebe. You can catch this Pokémon in these locations. When you trade him, he'll give you a Snowm, a great Pokémon if you are in the early game. The next NPC is located in Cascarapa by a Water Fountain. She's gonna want a Pau-Dian Whopper. So grab one from the first area in the game and then trade her. She'll be giving you a Jotonian Whopper. The blue one. The final NPC is located in Lavencia and they want a Pinchurchan. I grabbed one south of Lavencia on the beach. After you get this Pokémon, travel straight to her from this location and she'll give you a Hunter that will evolve into a Gengar.
