One of the rocks in your town will randomly give Bells when it is hit repeatedly. Note: To hit a money rock quickly, dig holes on either side of it and another hole behind you in order to trap your character in position. By doing this, you cannot recoil away after hitting the rock, and allows you to repeatedly smash it quickly.

After getting the Golden Shovel, use it to bury money. It will grow into a tree. Shake that tree and moneybags will fall from it instead of fruit.

On Bunny Day, dig up everything with a shovel. Get all the bunny eggs and open them. If they are candy, eat them. If they are bunny foil, keep them then see the bunny man in front of the main hall. After you get the prizes, sell them to Tom Nook and save the game. Play a different day, save the game, and start Bunny Day all over again.

Set the system date to Christmas Eve of any year in the future and the time to after 8:00 p.m. Walk around and find Jingle, a reindeer in a Santa suit. Talk to him and he will ask you two questions.
