"Petz Nursery" challenges players to take care of an array of household pets. Over the course of the game, your pets will mature and you'll accumulate goods and wealth. Even after you turn off your DS, this data will be stored on your game cartridge. If you want to start over, you'll need to delete this data. There isn't an in-game button to press that will do this for you.
Start the game.
Hold down the "Select" button as well as "L," "X" and "B" as the game is loading. You'll be prompted with a question: "Do you want to delete all game data?"
Answer "Yes" to the prompt. All your data will be erased and you'll be able to start over.
