Jack-in-the-Box Jitters

This is a mini-game exclusive to the Jack-in-the-Box Zombie. There will only be Jack-in-the-Box Zombies except in the waves, which there are 4 of. There will be Flag Zombies and Regular Zombies in the waves, and LOTS of Jack-in-the-Boxes.

Strategy
Try getting as much instants as you can, to prevent them from exploding. Chompers are a must, especially behind Wall-nuts because they are not single use. Magnet-shrooms can take the first few jack-in-the-boxes, but later there will be too many for them to be useful. Also it's good to take Doom-shrooms, before there are too many Jack-in-the-Boxes in your way. Cabbages and Kernels are out of the question because a Jack-in-the-Box Zombie has a columnpoint of 10 against the Cabbage-pult (more than the entire roof) and 20 against the Kernel-pult (WAY more than the entire roof). When you have enough Sun, Ninja-pult are a good addition because their projectiles do more damage. Melon-pults and Wall-nuts should be good too but only in the beginning and the apparently does not have much splash damage.
