Why Pea Pods?

Pea Pods are expensive, single-target plants, and the Challenge Zones are like Survival: Endless in that anything that attacks without AoE is useless. Pea Pods are only useful if you have Torchwoods too.

On top of that, you're obviously not prepared for rounds 30+, where the second zombie will usually be in a row without a bridge, and when a Seagull appears there, Iceberg/Potato Combo will not work.
