| Sunny Day|
Planted at least 3 Sunflowers.
There is not much of a strategy different than the general strategy for a level. Simply plant a Sunflower, wait for the recharge to pass (and collect sun in the process), plant another one, and then plant a third Sunflower or defeat the first zombie. After that, completing the level in any way should achieve Sunny Day. The total amount of sun needed to plant three Sunflowers is 150.
