You, your friend, and Dave were having a drinking night at the bar. It was a lot of fun, and things kept going until nightfall. Dave's house was the closest, so you all agreed that you would spend the night there,You were walking there when some zombies came out of the ground and tried to grab you. Startled, you ran, grabbed a chair, and hit one of the zombies, but... plants!?Plants, peas, shot at the zombies, killing them, Dave explained Dave:"Relax! This is normal, zombies always attack... I discovered these plants that have life, they can attack the zombies." You calmed down knowing that, then you and Dave went for a walk, you saw a sunflower making some suns, Dave then says Dave:"This is a solar flare; it produces sunlight that serves as fuel for the plants. If you add more plants, I discovered that tickling one makes it produce twice as much suns,How did I figure this out? I'm crazy!Take care of her and do whatever you want while I prepare Your things for you to spend the night." So Dave goes inside to prepare things, you stay there, the crew protecting you, and more zombies are coming, there are many... those crew alone wouldn't be able to handle it, you need sunlight, but the production is very...slow!You look at the solar flare, wondering whether you should make it produce more or not. Solar flare:"Hey!! I'm Solar Flare, like Dave said, you're his friend, right? We're all against the zombies, haha! But, are you human? I thought they were all extinct!"
