There are lots of NPCs in Stardew Valley. Only 12 of them, like Abigail or Sebastian, can be married. Others exist just to enrich the game and assign tasks to players. That's the purpose of Leo in Stardew Valley, and here's all the information about him.Leo in Stardew Valley: A guideLeo is a young boy who initially lived on Ginger Island. His parents were tragically lost at sea, and since then, he considers the parrots inhabiting the island as his family.At first, Leo is too shy to talk to the players. This changes after the latter makes friends with the island's parrots by giving them Golden Walnuts. This can be done by giving 10 Golden Walnuts to the first parrot sitting by the turtle.Ginger Island is the initial home of Leo, an NPC in Stardew Valley.

After reaching six hearts and moving away, he will live in a treehouse in The Mountain. He will visit his old home on Sundays and Mondays.Giving gifts is the best method to improve one's relationship with Leo. He loves duck feathers, mangoes, ostrich eggs and poi. It doesn't end there as he is also fond of dragon teeth, mango sticky rice, nautilus shells, quartz, rainbow shells, sea urchins and spice berries.Leo from stardew valley is YOUR shota bf <3 pic.twitter.com/GPHvux7Wcn— your fav is a shotacon 🍯🧸 (@shotafication) February 21, 2021Leo dislikes chanterelle, common mushrooms, daffodils, dandelions, ginger, hazelnuts, leeks, magma caps, pickles, purple mushrooms, salmonberries, snow yams, wild horseradish and winter roots.
