They grant the user unlimited energy for a set amount of time.Energy Toffee will be consumed and activated immediately after you purchase it. If you consume an additional Toffee while having unlimited Energy activated it will add time on top of your existing time limit. When the timer expires, Energy returns to normal. Energy will be at max when the Toffee expires and will include any overflow Energy that was gathered during that time.
