The Spikeweed Zombie is a zombie with a head of a Spikeweed that digs underground. It does 3 bites of damage to every plant it passes through. It can only be killed by lobbed-shot plants when underground. Magnet-shroom can make it stop digging and come out.
- This and Spikerock Zombie share almost the same traits as the Digger Zombie, except that the Digger Zombie can't be attacked by lobbed-shot plants, while the hybrids can.
