Well, not too much.
 * A world set in a cave (or cold cave) with dark environment, where plants can't detect zombies unless when lit.
 * A world set on a side of a snowy hill (or mountains) with an occasional snow avalanche, which covers the entire screen with S N O W I E R S N O W S which stun any plant in it. The snow could be removed with Hot Potato or thawing plants.
