Much like inviting her to live in your town, you will need to scan the amiibo card for Étoile to unlock her furniture set. She doesn’t need to move to your city or island to receive the furniture set, but the amiibo needs to be scanned. Once it has been, the furniture is available to order via the ATM in the Town Hall, which goes for all Sanrio amiibo cards. The furniture sets will be underneath the special goods menu.
