Survive the Storm would be a level in Ice Age. It would be level 20.
It's pretty much a Locked and Loaded level.
What happens is that Every few minutes a storm comes and it freezes all the plants. Then you use Light Bulb to unfreeze the plants, then use Blover to blow away the storm. Even the zombies freeze in the storm but the Light Bulb can't unfreeze those guys. Then it would be a normal level again, then a storm. It's 4 waves. I think this is a pretty cool idea.
