Ducky Tube Zombie

The Ducky Tube Zombie is the basic water-traveling zombie and can only be found on levels that have the pool. When encountered, it will walk up to the pool's edge, jump into the pool, and move across the water. During the final waves of the Pool and Fog levels they can also suddenly appear from underwater, similar to Graves in Night levels and the "ambush zombies" dropped by Bungee Zombies in Roof levels. The Ducky Tube Zombie is actually four separate land zombies adapted for the water; the regular Zombie, the Conehead Zombie, the Buckethead Zombie, and the Flag Zombie.

In ZomBotany 2, all ZomBotany Zombies except the Squash Zombie have ducky tube versions.

Trivia

 * Because they walk up to and jump in the pool, the player can kill them before they even get in the water if he/she has strong enough defenses. If this happens, they will fall on top of the water. Oddly, their ducky tube will disappear.
 * The Ducky Tube Zombies that appear at the end of the level will, for some reason, have pieces of seaweed on them, which is strange. Although there should not be seaweed in a swimming pool, they may have seaweed on them because they came underwater from somewhere where there was seaweed (i.e. the sea).
 * Oddly, a Ducky Tube Zombie's Ducky Tube has a patch on it. With the patch, the Ducky Tube should not float if it has a patch. But it still floats for some reason.
 * The pool may just be low-leveled, allowing the Ducky Tube Zombie to walk.
