Slops appear in Chrono Trigger (DS) as a consumable item in the Arena of the Ages. If given to your monster, the monster will use it and regain some HP. If given to the monster during training, its Max HP will increase. Like all the other Arena Items, it cannot be used in the main storyline, and is lost if you give your monster another item. They can only be acquired from the Nu's shop in the Arena, and it costs 100 G each.
