After you first repaired the fountain, it gives you the opportunity to get 40 energy three times. After that, it breaks and you can fix it again. While the fountain is broken, it gives 5 energy. If you fix it a second time, then again you can get 40 energy three times. In order to fix the Fountain, you need special spheres that can be obtained on Forgotten Island.
