To recruit the first neighbor in Animal Crossing New Horizons named Blathers, you will need to collect 5 different fish and/or insects. After you collect the fish/insects, show them to Tom Nook who will then receive a call from Blathers who announces that he will be moving to the island. Tom Nook will then task you with finding a spot for Blathers. Once you found the spot you would like to place Blather’s tent, open up your inventory by selecting “x” then select Blather’s tent to place it. After you complete this task, return to the Resident Services (where Tom Nook always is) to trigger a brief dialog scene. You will then need to wait a day in real life. The following morning Blathers will appear in his tent with a new task for you!
