What to Do With Gyroids in ‘Animal Crossing: New Horizons’

Each gyroid behaves slightly differently, making different voices or movements depending on its type. In New Horizons, when you turn them on, they will sync themselves to whatever music is playing in the room.

In previous games, at most eight gyroids could be turned on in one room at a time, but in New Horizons, players can turn on as many gyroids in one room as they please — which can make for some chaos depending on how big your collection is.
