If you have at least 50,000 Pet Points, go to Town Square and buy a lot of items from each store. The stores will upgrade until they are skyscrapers. When your inventory is full, go back home and place all the items on the lawn. Note: You cannot place items from the bakery on your lawn or sell them. Then, go into Grab mode and sell all the items for money. If you keep doing this, the stores in Town Square will upgrade and so will the money in your pocket. When the stores are full upgraded, go to the most valuable item and keep buying that item until your inventory is full. Then, go back home and sell all the items for more money. Note: You may need more Pet Points to complete this trick.
