Bug Zombie

 is a zombie encountered in Plants vs. Zombies 2 that appears in Lost City. The bug can carry Basic, Conehead, or Buckethead Adventurer Zombies, i.e. variants of the basic zombies. It greatly improves the zombie's speed making it easier for the zombies to advance. Kernel-pult's butter can destroy the bug instantly, while using Blover or Hurrikale will kill both the zombie and the bug. The bug has separate health from the zombie it's carrying. When it is destroyed, the zombie will fall to the ground and advance normally.
