Conehead Zombie

The Conehead Zombie is the third zombie the player encounters in Plants vs. Zombies, after the ordinary zombie and the Flag Zombie. It is a zombie with a roadcone on its head for protection. While it is relatively easy to defeat, it is much harder to eliminate than both the Flag Zombie and the ordinary zombie. It has somewhat high health, but it can only be directly hurt once the cone has fallen off its head.

Suburban Almanac Entry
 Conehead Zombie 

His traffic cone headpiece makes him twice as tough as normal zombies.

Toughness: medium

Conehead Zombie shuffled mindlessly forward like every other zombie. But something made him stop, made him pick up a traffic cone and stick it on his head. Oh yeah. He likes to party.

Plants vs. Zombies
The Conehead Zombie absorbs 28 normal damage shots and its appearance changes upon an absorption of 7, 13 and 18 when the roadcone is destroyed and 23 normal damage shots before dying at 28 normal damage shots.

Plants vs. Zombies Adventures
The Conehead Zombie absorbs 12 normal damage shots and its appearance changes upon an absorption of 3 and 8 when the roadcone is destroyed and 11 normal damage shots before dying at 12 normal damage shots.

Strategies
Even though he takes more hits than the regular Zombie, this zombie is not at all difficult to stop. A Snow Pea, two Peashooters, or a Repeater can take it down easily. It is weak to almost all strategies, so your basic setup should take it out. However, do not underestimate it, as it can be a threat in the early levels and the beginning of the game. A single Peashooter can be sufficient to kill one, but two or three work better, especially if there are multiple zombies to be killed. A single Peashooter is also enough to kill a Conehead Zombie before it encounters the square that the Peashooter is on.

I, Zombie Endless
After the normal zombie is replaced by the Imp, use this zombie for the lanes you want a small amount of damage absorption. Their cones aren't affected by the Magnet-shroom, so use them to take out the Magnet-shroom if it isn't well defended. However, be careful not to send them to a highly defended lane. For puzzles involving Scaredy-shrooms, time Conehead placement and location so the most Scaredy-shrooms in a lane are hiding, allowing Coneheads to walk down the row with no or minimal harm.

Trivia

 * In the Suburban Almanac, it's stated that a Conehead Zombie is twice as tough as a normal Zombie, but in fact it's 2.8x as tough as one.
 * Maybe it is talking about the Cone, which has 18 hits, almost twice the HP of a normal zombie, still not exactly twice as much as a normal zombie.
 * Most likely it is stating that two Peashooters is the number of Peashooters required to kill it without getting bitten, while one is required for a normal zombie. (Although, if planted in the left most column when it first appears, one Peashooter is enough)
 * The Conehead Zombie is the third most frequently occurring zombie (other than regular zombies and the Flag Zombie), as it appears in every level but levels 1-1, 1-2, 2-1, 4-5, ZomBotany, ZomBotany 2, Pogo Party, Bobsled Bonanza, Heavy Weapon, BOMB All Together!, Homerun Derby, Portal Combat, Zombiquarium, Air Raid, Air Raid (Hidden Mini-game), Ice Level, Squirrel, Vasebreaker and first 7 I, Zombie levels.
 * Some of the Game of the Year edition packs come with a punch-out cardboard cone that can be placed on the head of the zombie figurine. This cone will require minimal construction first, possibly with the aid of tape.
 * It is unknown how the roadcone could protect the Conehead Zombie from projectiles and some plants like Spikeweed and Spikerock, as they mostly hit the other body parts.
 * The Conehead Zombie, the Buckethead Zombie, Screen Door Zombie and the Trash Can Zombie are the only zombies that can degrade into a normal Zombie.
 * If Plants vs. Zombies: Game of the Year Version was purchased on Steam before May 5th, 2011, the Pyro from Team Fortress 2 will be awarded with a Dead Cone hat.
 * The top of the cone can be seen through the fog if it appears in the top row of a fog level.
 * In anything Wall-nut Bowling-related and Whack a Zombie, it takes two hits for a Conehead Zombie to die.
 * The Conehead Zombie, along with two normal zombies, appears on the loading screen.
 * This is the first zombie to have some armor.
