These are all items that can be purchased from your clients in the RV (and in the case of your alien client Lepetal, also in the locker room). Deshawn has the BBQ for sale starting from level 27, Lepetal has the Fan from level 30, and Hawk has the Statue from level 34. For all of these items, click on the client, look at the bottom left of their deal screen and click on the item. Follow instructions to purchase. Once the items are added to your game, you can use them to give you an energy boost as you play!
