Spiky Seed

Spiky Seed is a plant unlocked in Abandoned House. It can latch onto zombies.

Effect
Spiky Seed shoots spikes every 1.5 seconds that deal 1 NDS. Unlike Cactus and Cattail, they can't shoot down balloon zombies. Every time Spiky Seed shoots at a zombie, the spike has a 5% chance of latching onto the zombie, instead of damaging it. After a randomly determined amount of steps, the spike will fall off the zombie and grow into another Spiky Seed. If the spike falls off where there's already a plant (Apart from pumpkins, lily pads or anything like that), it won't turn into a Spiky Seed. The spike won't grow into a Spiky Seed if it falls off in water or on the roof, either. As a weakness, it has extremely low health. Spiky Seed's spikes will never latch onto bigger zombies (EG Gargantuar) or bosses.

Strategy
Since it is very weak health-wise, it is recommended to plant it near the back and/or place it inside a pumpkin. Planting them in lanes with fast zombies will let spikes fall off and turn into Spiky Seeds quickly.

Trivia
Spiky Seed is based on a Burdock, a plant which does the exact same thing as Spiky Seed (Minus the shooting part).
