So, my siblings played animal crossing in my switch, and so they were added to the same island as I made. So, I’ve got them as residents, 3 of them. I’m just curious if how many more villagers will be added to my island with having my siblings too in my island... HELP

you can have 10 animal residents and up to 8 human players on one island. having more or less human players won't affect the number of animals you can have
