In Animal Crossing: New Horizons, the furniture you place in the three plots does not determine the specific villager that will move in. Instead, the villager that moves into each plot is determined by the villager hunt or autofill process, which is influenced by the island’s overall villager population and the specific villager that is available to move in at the time.

Here are the steps to get the first three villagers and place the plots:

1. Obtain the Housing Plots:
– You can obtain the housing plots from Tom Nook during the villager house development quest.

2. Place the Plots:
– Place the plots wherever they fit on your island. It’s recommended to place them in a large open area to accommodate the furniture and future expansions.

3. Furnish the Plots:
– Each housing kit comes with a list of required furniture items. You can build these items using DIY recipes or purchase them.

4. Villager Hunt or Autofill:
– If you choose to villager hunt, you will need to go on a Nook Miles Island Tour and catch the villager you want to move in. This process involves using Nook Miles tickets to visit mystery islands and interact with villagers.
– If you choose to autofill, the game will automatically select a villager for each plot based on the available villagers on your island.

5. Submit the Furniture:
– Once you have the furniture items, submit them to complete the plot setup. If you are villager hunting, do not submit the furniture until after the hunt to ensure the villager is captured and moved in.

6. Move-In Process:
– After submitting the furniture, the villager will move into the plot. If you autofilled, the game will notify you when the villager has moved in.

In summary, the furniture you place does not determine which villager will move in; instead, it’s the villager hunt or autofill process that decides which villager will inhabit each plot.
