Spikerock is the upgrade of Spikeweed, and is purchased from Crazy Dave's Twiddydinkies for $7,500. It is a passive attacking plant, dealing high damage to any zombie that walk on it. It costs 125 sun to upgrade a Spikeweed to a Spikerock, for a total cost of 225 sun. It usually deals ten attacks in groups of two, (each attack doing one damage) for every normal speed zombie that passes unimpeded over it (exceptions include zombies that come in a group, when one zombie gets on just after the Spikerock fires). Spikerocks will pop tires, up to nine Vehicles (Zombonis and Catapult Zombies) before dying, with one of its large spikes breaking off with every three vehicles. When a Gargantuar attacks it, it will have the same effect as when vehicles roll over it, without the Gargantuar dying. Since the Spikerock attacks from below, it bypasses shields and fast attacking zombies.

Being the most metal plant, Spikerock has decided to hold his ultimate metal plant concert at Madison Rock Garden. Tickets have been sold out for many harvests.

Upgrades

Plant Food

When fed Plant Food, it temporarily fills the row with other spikes poking up from the ground and pulls zombies to where the Spikerock is. This lasts for 4.5 seconds. Like the Spikeweed, the secondary spikes can destroy rolling objects and damage zombies being pulled towards the Spikerock. When in effect, if the Spikerock is in a minecart, the minecart cannot be moved.

Overview

Plants vs. Zombies

The Spikerock absorbs nine smashes and its appearance changes at three smashes and six smashes before finally being dead at nine smashes. It loses one of its large spikes when smashed three times. It will damage zombies at 10 HP of damage per a regular zombie's patch speed. It will automatically kill Zombonis and Catapult Zombies by popping their tires.

Plants vs. Zombies 2: It's About Time

The Spikerock absorbs three rolling objects and its appearance changes at one rolling objects and two rolling objects before finally being dead at three rolling objects. It loses one of its large spikes when rolled over one time. It will damage zombies at ten normal damage shots per a Basic Zombie/Mummy Zombie/Pirate Zombie/Cowboy Zombie's speed. it will automatically destroy a Barrel from a Barrel Roller Zombie and kill a Pianist Zombie by destroying them. Also, when a Gargantuar smashes a Spikerock, it also degrades. It takes three smashes for a Gargantuar to kill it.

Strategies

Plants vs. Zombies

Use the Snow Pea, Winter Melon, or Ice-shroom to slow the zombies, so they spend more time being attacked by the Spikerock. A Snow Pea and a Spikerock is particularly cost effective, but if Winter Melons are used, all the zombies in an area get slowed. You can also use the Kernel-pult as if it uses a butter and a zombie is standing on a Spikerock, it will continue to take damage.

Plant the Spikerock in front of a Wall-nut, Tall-nut, or Pumpkin. Most zombies do not attack it, and are continuously damaged as they try to break down the defensive plant.

The Spikerock is uniquely capable of withstanding multiple strikes from Gargantuars. This considerably slows Gargantuars and allows extra time for your other defenses to attack, since, unlike other zombies, Gargantuars will stop to destroy the Spikerocks.

The Spikerock can also damage Newspaper Zombies, Screen Door Zombies, and Ladder Zombies without destroying the shield first.

Bobsled Bonanza Mini-game

As it can pop multiple tires, the Spikerock is an incredibly useful plant to use on this level. It is a good idea to plant a column of Spikeweeds at the edge of the ice to deal with Zombonis, but they should be upgraded to Spikerocks as soon as possible. To deal with the Zombie Bobsled Teams, there should be an additional Spikeweed behind the Spikerock (as the zombies can only take one normal damage shot after passing over the Spikerock, although when first setting up it is best to plant three).

Survival Mode

Though useful on the early waves, Spikerock is not recommended for Survival: Endless due to overlapping Zombonis, Catapult Zombies, and assorted Gargantuars. Often, a Spikerock may be killed shortly after it was placed down. However, Spikerock is ideal for any survival level, easy or hard. The ability to kill multiple Zombonis, that if left alone, will crush your setup, is a superb one by any fact. It can also save your offensive plants some time, as one Spikerock can kill a regular zombie without help. Many strategies use Spikerocks planted on the backmost column in Survival: Endless to kill Digger Zombies.

Plants vs. Zombies 2: It's About Time

One example of scenario in Dead Man's Booty

Spikerocks are best way to stop zombie horde as Peashooting Plants alone are only capable of dealing with zombies that are in the front lines. This, along with the Winter Melon or Melon-pult, Pea Pod, and Tall-nut or Wall-nut can immediately hold off massive zombie incursions, especially in Dead Man's Booty because it will stop Imp Cannons from detonating. However, it is not advised to bring one when Gargantuar Pirates or Barrel Roller Zombies come into greater concentrations.

Spikerocks in Dead Man's Booty - Level 129 by JemCel03. There are Spikerocks placed at the edge where Imp Cannons are.

In Big Bad Butte, you can use Spikerocks to stall Wild West Gargantuars by placing them in Mine carts through the use of dragging up or down. Also, it serves as a temporary block-off against Zombie Chickens (although this may have to require manipulating more than one minecart).

Spikerocks are very useful to stall Gargantuars. A good strategy to stall Gargantuars for a short while is to plant a Spikerock in front of a Gargantuar. When the Gargantuar is about to smash it for the third time, dig it, You will get Shovel Bonus or Shovel Boost sun.

Trivia

Specific to Plants vs. Zombies

• Jack-in-the-Box Zombies, Zombonis, Catapult Zombies, Bungee Zombies, Jalapeno Zombies, Gargantuars, and Giga-gargantuars are the only zombies capable of damaging Spikeweeds and Spikerocks.
• When a Spikerock is planted in one of the two bottom right squares, it will be higher up than other Spikerocks. This is so you can see them over the level progress bar.
• The Spikerock is the most durable plant in the game because it can withstand nine Gargantuar's smashes and nine tire pops of the Zomboni and Catapult Zombie. Despite its resilience, it still only takes take one Jack-in-the-Box Zombie or Jalapeno Zombie explosion or Bungee Zombie grab to destroy a healthy Spikerock.
  • Jalapeno Zombie can destroy something biologically rock, as its melting point would be massive and take temperatures vastly beyond the output of a Jalapeno Zombie, and the fact that rock is inflammable makes the very brief blast of the Jalapeno Zombie seem even less able to destroy or melt rock.
• Biologically, the Spikerock is not a plant; it is a rock.
• The Spikerock can still harm Bungee Zombies even though they are in the air.
• The Spikerock is one of four plants that have names which do not involve plants, with the others being the Grave Buster, the Gold Magnet, and the Chomper.
• This is one of only two plants that change appearance but cannot be healed with Wall-nut First Aid, the other being Garlic.
• It is unknown how the Spikerock can make the Catapult Zombie's catapult machine or Zomboni's ice machine explode by just popping the tires.
• The Spikerock and the Squash are the only plants that can survive Gargantuar smashes and a vehicle.
• The Spikerock is the only upgrade plant that can't be eaten.
• On the iPod version, spikes will not fall off Spikerocks.
• The Spikeweed, Spikerock, Potato Mine, Grave Buster, Tangle Kelp, Sea-shroom, and Flower Pot are the only plants that cannot be planted on a Lily Pad.
• The Spikeweed, Spikerock, Cattail, Grave Buster, Tangle Kelp, Sea-shroom, and Lily Pad are the only plants that cannot be planted on a Flower Pot.
• The Spikerock can damage a Gargantuar if it tries to smash it.
• The almanac entry of the Cob Cannon, Garlic, and Spikerock are the only ones where real places are written in (Harvard, New York, the Uni Brüssel, and Europe).

Specific to Plants vs. Zombies 2: It's About Time

• It can now be planted as a normal plant instead of having to be planted on a Spikeweed like normal Upgrade Plants. It shares this trait with the Twin Sunflower and Winter Melon.

• The Spikerock now costs 250 sun. In the original game, it costs 225 sun to get it, as Spikeweed costs 100 sun and Spikerock 125 sun, which means it needs 25 more sun in this game.
• Its almanac entry says its body is made of metal, even though it is called the Spikerock. Plus, its health has changed from nine times being rolled over to three times being rolled over. This is actually ironic because metal is normally more resistant than rocks.
  • Its health has also been changed from nine Gargantuar smashes to three Gargantuar smashes.
• Spikerock makes a different sound when stepped on by a zombie. The sound is similar to air being leaked out of a bag.
• There is a rather helpful glitch that happens in Endless Zones with Spikerock. All Spikerocks on screen will sometimes become indestructible and can take repetitive smashes from Gargantuars.
  • This seems to happen when reloading a game. This is also related to what happens with a Twin Sunflower's Plant Food ability, which, is unfortunately no longer available.
• Like Spikeweed, whether a Spikerock has its costume or not, when it's attacking a zombie, it appears without the costume.
• According to the credits, Spikerock was voiced by Taz the Dog.
• Strangely, Spikerock cannot pop Shield Zombie's treads.
• Unlike the Spikeweed, the Spikerock's costume disappears when it hurts a zombie normally.
• In the Chinese version, Spikerock's costume will affect its Plant Food by making the duration of the Spikerock bringing zombies to it longer, and when the zombies are pulled to the Spikerock, it will make the zombies dizzy and confused and eat their allies, similar to a Hypno-shroom the Spikeweed's Chinese costume effect.
