Energy is a function primarily used in Where's My Water? 2. Every time you play a level, the energy will deduct. If you run out of energy, you must wait for it to restore in order to play/replay any level. Refilling your energy will cost real money, so it's best to wait for it to refill. As of today from many feedback, Disney has removed the energy system. Cranky is shown eating the Energy System and a player will get a reward if he/she has purchased an energy booster pack.
