Zombie Sewer Gnome

Zombie Dave is a boss in the Campaign Mode of Plants vs. Zombies: The Cure. He has 1500 NDS of health, and is seen in The Sewers.

Traits
Zombie Sewer Gnome is a zombie-allied version of one of the Brothes Gnomus from PvZ:GW2. As he is a gnome, the Zombie Virus cannot take hold, but he decided to cooperate with Zomboss after his brothers fell. He does not like the zombies much, but cooperates with them anyway because of the threat of death.

Behaviour
Zombie Dave has 1500 NDS, with five stages of 300 NDS each. In the first stage, he will deploy zombies from The Siege quickly, and will smash any plants that get close. On the second stage, he will kick Dirty Water at the first column of plants, then place zombies in the Dirty Water. His third stage is a repeat of the second stage, only this time he uses all encountered zombies. In his fourth stage, he will knock down all Planterns, and then place random zombies in the dark. During his fifth and final stage, he will cease deploying zombies and begin to attack alone, using lightning bolts that do arcing damage shot from his metallic mushroom.

Strategy
As this boss fight is in the sewers, you will need Hose Rose and Lily Pad (and possibly Macadamia) to combat the water, and Moonflower (not Plantern, as he will smash it). As this boss has 1500 health, creating a defensive line that will hold back most zombies, along with lots of Taropedo Launchers in the back, can chip him down. However, when he enters his final stage, arcing damage will destroy any plants that have not been toughened and are close to other plants. Hence short-ranged plants will not fare well against him.

Trivia

 * Zombie Sewer Gnome is the only boss that is (technically) not a zombie.
