The challenge is to reach the final stage using a limited amount of energy potions. With a lengthy stages and only seven energy potions, you'll have to strategize between the combination of cookies, pets, power upgrades, relay, and the treasure equipped.

Try Zombie Cookie with Brain Gum. That will allow you to reach the final stage, although will not score much.
