Grenadia

The Grenadia explodes when planted, doing massive damage in a 3x3 area, but also spreads seeds and pulp within a 5x5 area. The black, hard seeds act like already armed Potato Mines, but they only do half-massive damage, and it scatters five of them around. If a seed stays for five minutes, it will grow into another Grenadia.

The pulp will slow down Zombies that walk over it, and after five Zombies walk over it, the pulp will disappear. It spreads pulp on five random spaces too.

Seeds and pulp can land on spaces that already have plants on, so keep that in mind. Also, seeds can't grow into another Grenadia if they are on a space with another plant, unless it's something like a Pumpkin, and the pulp and seeds can end up in water, on roof tiles and so on, but seeds can't grow into a Grenadia if that happens.

If you can make a picture, please do.
