PVZ 1

After defeating a small wave of Zombies with the use of Peashooters, a Bloom&Doom seed suddenly dropped from one of the Zombies, that being, of course, Sunflower!

So, upon another wave starting, you placed down the Sunflower, getting the info from Crazy Dave that she produces Sun for you to place more plants.

Which, for now...well, Sunflower was not doing much, just...bopping her from side to side, listening to the life-giving jazzy rhythm of the Earth itself...I don't think she even realized you were there to be honest...
