Amiibo are figurines and cards that you unlock in-game
experiences or items in various Nintendo games. New Leaf gained
amiibo functionality with the Welcome Amiibo update in 2016. The
character of Wisp was introduced, a fat little ghost who lives
in a magic lamp. If you select A when standing in front of the
lamp, Wisp will pop out and ask you for a body to inhabit. If
your figurine is for an Animal Crossing NPC like Tom Nook or
Isabelle, Wisp will take their place in-game and the character's
RV will appear in Harv's campsite, where you can buy their RV
items for MEOW coupons. Villagers have amiibo cards, and you can
invite them to appear in Harv's campsite, but you can also
invite them to live in your town.
Some amiibo from other games work, too, unlocking
unique crossover characters, such as Cece from Splatoon, Wolf Link and Epona from Zelda,
and Felyne from Monster Hunter. There's also villagers created
for other tie-ins, like 7/11 and the Japanese supply company
Fueki.
In New Horizons, you can use amiibo in different places, but it
only supports Animal Crossing characters (and the two Villager
Super Smash Bros. figures). Characters can be invited to take
pictures on Harv's island, where you can decorate rooms and put
characters in. You can invite characters to have coffee at the
Roost, and you can also design their vacation homes in the Happy
Home Designer DLC. After scanning an amiibo, you can also order
their poster from Nook's Shopping. And, most importantly, you
can invite villagers to your campsite.
If you have an amiibo card for a villager, you can scan it at
the Nook's Terminal in Resident Services. This invites the
villager to stay in the campsite. This only works for villagers
that aren't in your town, not NPCs like Tom Nook or Rover. After
inviting them, you can talk to them at the campsite and they'll
request you craft an item for them. If you invite them three
times, each time crafting an item for them and giving it to
them, they'll suggest moving in. If you say yes but you don't
have any empty plots, you can pick which villager moves out.
We own two official Nintendo amiibos, a Tom Nook figure and a
Mac amiibo card. We've used the Mac amiibo card to get Mac in
Space and in Gravity after attaining him naturally in Tuesday.
The coins are not official, and we got them from
MilkPrince on Etsy. They're so cute, and they work exactly like an official
amiibo card would. We've used them so far to move Coco into
Gravity and Winnie into Space.
