The "Kaufisland" experience is a collaborative venture between Kaufland, a German supermarket chain, and Animal Crossing.
Kaufisland is not just a virtual supermarket but a part of a broader initiative to emphasize sustainability, reflecting Kaufland's real-world sustainability strategy named "Machen macht den Unterschied" (Doing Makes the Difference)​2​. A character named Phil Leita, whose name phonetically sounds like "Filialleiter" (store manager in German), is introduced as a sort of face for the virtual store​3​.
This virtual venture allows players to experience the grocery retail environment while also engaging with sustainability concepts in a playful, interactive setting.
