Ice Bean

This plant is, well, cool. It prevents plants from overheating during Noon. In ordinary levels, like Pool, it covers the square with snow, or, in the case of water, turns the water into ice. Water with a crater will lose its crater but still become ice, but if planted over a land-based crater, it will make it a snow-covered crater instead. Also, if planted on a square occupied by a zombie, all the zombies on the square are frozen solid, but they sustain no damage. It's crucial to Noon levels.
