After discovering that challenge was there, I tried it, and beat it easily. It's not actually that hard, just collect as much sun as possible and rapidly click the Peashooters when zombies are in their perked range. Bring backup lawnmowers as your boost, and freeze any Barrel Zombies that lose their barrels (which should be all if them).
