The peach is a fruit that is fed to the Brontosaurus,the Stegosaurus,Ram,and the Mech Mouse. To get the fruit you need to get a level 8 animal that can climb. You will then go to the dinosaur island which is by the desert and rain forest. Climb up the rocks until you get up and you will find bunch of peaches ready to harvest. The peach trees usually grow for 30-40 minutes until they're ready to harvest.
