3ds Animal Forest can't buy exterior decoration.

Hello, I want to ask what happened when 3ds Animal Forest couldn't buy exterior decorations. 3ds Animal Forest can't buy exterior decoration because of insufficient money. Because the exterior decoration of the 3ds Animal Forest costs 1800 gold coins in the game, covering an area of one square meter, there is not enough money to buy it. Animal Forest is a video game developed and manufactured by Nintendo EAD, which was released in Japan on 200 1. Because of its complexity, the game occupies 57 units of the memory card. The memory card has been connected with the game itself, and it contains a gift file that occupies one unit of memory.
