Ducky Tube Zombie

The Ducky Tube Zombie is the basic water-traveling zombie and can only be found on levels that include 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. 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, the various plant-zombie hybrids also have ducky tube versions.

Suburban Almanac Entry

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.
