Balloon

The balloon in this game is red and has a scary face with mean eyes and fangs drawn on it. It belongs to Balloon Zombie and it is used to bypass your defense. It is technically an armor as it gives the zombie a special ability and will take 1 hit for its owner before being popped. Having said the above, it is neither a shield nor headwear but can still protect its owner from a very small amount of damage, and thus belongs to a unique category of armor and is the only one so far belonging to its category. However this is subject to change as soon as PvZ 2 is released. Only absorbing 1 Normal Damage shot, it is the weakest armor in the game. The balloon's only weakness is a Spike from Cattail and Cactus. The balloon is also seen when you reach 1.000 points in the leaderboard.It's owner is nowhere to be seen.
