Preset Sunflowers is a Brain Buster exclusive to Ancient Egypt in Plants vs. Zombies Online. In this Brain Buster, sun-producing plants cannot be used and the player must rely on the Sunflowers already placed on the lawn as their production of sun. Unlike Save Our Seeds, these Sunflowers are not considered endangered and there is no direct penalty for losing them. However, doing so will cut the player's sun supply, and the player must minimize their plants' death on the second and the third level to earn a star.
|I (Level 10-2)||Five||One||Never have more than 20 plants (excluding Sunflowers)|
|II (Level 10-3)||Six||One||Don't lose more than 2 plants|
|III (Level 10-4)||Five||Two||Don't lose more than 1 plant|
- Because the player cannot choose the sun-producing plants, these Sunflowers cannot be upgraded to Twin Sunflowers.
