Melvin

Overview
Melvin is an NPC who moves onto the island after the player has a house, enough total spending, and more than 1 heart of relationship with him. He owns and runs Furniture Shop Deed, which becomes available once he settles in.
He will only visit if the player has upgraded their tent to a house by talking to Fletch. After the requirements are met, Melvin can ask to move in. Purchases made from the catalogue do not count toward the spending requirement.
Melvin Furniture is open from 10:00 am to 5:00 pm, and it is closed on Tuesday and Thursday. Like other NPCs, Melvin can unlock the "Let's hang out!" option once the player reaches 2 or more relationship hearts with him; this becomes available on his day off or after work.
Melvin’s dialogue reflects his role as a furniture maker, and he also comments on a range of island activities and items, including farming, diving, cooking, weather, and common tools and creatures.
