Heal Zombie and Vampire Zombie are the only Spawnable Zombies that can heal.
If there no injured allies around, it will go around hitting plants with its flag, like the Flag Zombie.
It does not actually have its heal station on its back until it reaches an injured zombie.
It spins when it activates its healing station.
It is the second zombie to hold a flag (the first being Flag Zombie and all of its variants)
The Heal Zombie, was used for the "Harry the Healer community challenge" where the players of Garden Warfare had to restore a certain amount of health points to allies using the Heal Zombie. Restoring 700,000 health would reward a Rare Pack, and 1,400,000 health restores would yield an Ultra Pack, the event was concluded on February 19. In the end the community completed both challenges. The challenge was made by a YouTuber named ZEROxFUSIONZ.
The flag has a revival symbol instead of a healing symbol.
It goes first on its injured summoner instead of staying or following the closest zombie injured around.
In Garden Warfare 2, it will sometimes turn back and forth while it is healing, resulting in jerky movements.
