You cannot get to a specific island called "Money Island" in Animal Crossing. The game does not feature a dedicated island for earning bells, the game's currency.
However, you can find ways to earn bells on various islands, including:
- Mystery Islands: You can visit these islands through the Nook Miles Ticket system. Sometimes, you will encounter special events like "Money Rock" events on these islands, where you can hit the rock multiple times to gain a large amount of bells.
- Visiting Friends' Islands: When you visit a friend's island, you can help them with tasks like catching bugs or fishing, and they may reward you with bells.
Remember, the best way to earn bells is through consistent gameplay, including completing daily tasks, selling items, and exploring your own island.
