Spikerock is the only plant over 200 sun not allowed. No Power-Ups, Boosts, or Plant Food is allowed (except for the two that you start off with). You may also not lose a single lawn mower.

Spikerock makes this challenge too easy, so its use has been banned. Dude, Laser Beans!

Five Laser Beans are one of the cheapest strategies for that level, and is ten times more effective than Spikerocks!
