A question for you, my Ignoble Foes! Hast thou noted how violent thine plants become upon consuming Plant Food? Perchance, has thou wondered what Plant Food is truly made of? Verily, I shall tell thee. It's zombies! Plant Food is made out of zombies!
The Zombot Dark Dragon can summon random zombies across the field frequently and more dangerously than the other Zombots faced before. In addition, this Zombot still has a two lane destroying attack (breathes fire instead of rushing), and has another attack that will rain down Imp Dragons. Luckily, the player is given a boosted Magnet-shroom for the fight, which can counter the Zombot Dark Dragon's attacks. However, only one will be given, so to use it again, the player must dig it up. The Jester Zombie can be difficult to defeat early, as Pea-nut and Kernel-pult provide ammunition for the Jester Zombie, and two columns of Fume-shrooms are recommended to defeating it, which can take some time to set up. Wizard Zombies can easily overwhelm the player in large groups, so be ready to take them out as fast as possible. Knight Zombies can easily be countered by the given Magnet-shroom. The Zombot Dark Dragon can have some devastating results if not countered properly. For example, it can rain a few Imp Dragons, and then use its fire breathing attack. Since the Imp Dragon is invulnerable to fire attacks, it will live and be extremely deep in defenses. Using Magnet-shroom strategically is the key to winning. Also, Puff-shrooms are nearly useless in this battle, as they are too weak to combat most zombies, and they provide more projectiles to deflect for the Jester Zombie. However, using Plant Food on Puff-shrooms is not a bad idea. Dark Ages Gargantuars can be summoned many times during the second phase, which can easily result in a loss. Using Plant Food on Fume-shroom can help extremely, especially if the Dark Ages Gargantuar is knocked into the Zombot Dark Dragon where it will be instantly defeated. Additionally, letting the Zombot Dark Dragon do its flame breath attack will also kill it as well.
Note: The Magnet-shroom will always be boosted, even if it is not in the Zen Garden. This is to help deal with the Zombot Dark Dragon's weakness.
You can only ever have one Magnet-shroom at any given time in this level. After its boost wears off, dig it up, and likely it will be one of the next four plants to arrive on the conveyor-belt. Use this to your advantage, and plant it to stun the Zombot Dark Dragon before it attacks and summons zombies. This is also useful for dealing with Knight Zombies and Wizard Zombies simultaneously.
When the dragon's cheeks puff up, it means its about to breathe fire (it is a variant of the charge attack). When this happens, immediately give Plant Food to the Fume-shroom only or plant Magnet-shroom as they can stop the Zombot. Do not hesitate and do not make a mistake or your plants will be burned.
If you get Magnet-shroom, use it immediately, then dig it up to use it again but only if Buckethead Peasants come in large numbers. Be sure to place it on where the Zombot Dark Dragon is to damage it.
Immediately plant as many plants as you can to kill the Wizard Zombies quickly. Remove the Puff-shrooms when you see Jester Zombies. Pea-nuts make an excellent decoy in this level in order to lure the Jester Zombie.
Kernel-pult is not compulsory, it will only help you as the Last Resort or stun the zombies, especially Wizard Zombies. However, its projectiles can be deflected by Jester Zombies, so make sure that there is at least one Fume-shroom on each lane.
Imp Dragon Zombies are not a threat, except when the Zombot Dark Dragon uses its flame attack. Kill them quickly.
Note: Each lane should have at least one Fume-shroom in case of Jester Zombies.
Dark Ages Gargantuars will be summoned during this phase and are considered as the largest threat. Use Fume-shroom's Plant Food Upgrade to weaken the Gargantuars, as once it is pushed back to the very front of the lawn, the scorched tiles will burn it. However, Zombot Dark Dragon will become more relentless in this phase and it can call more than one Dark Ages Gargantuar in some occasions. Be sure to dispose all of them before they could cause more serious havoc.
Wizard Zombies and Jester Zombies will not be summoned in this phase, therefore, you do not need to worry about them.
Zombot Dark Dragon will use its fire breath ability here, removing all of your plants in a 2x2 row. This is identical to its charge attack from hisfirstfourcreations. But it will not allow you to replace lost plants immediately.
Fill Puff-shrooms on the sixth and seventh column to attack Dr. Zomboss.
The Zombot Dark Dragon will always target Magnet-shrooms first with its fireballs.
Before starting the battle, Dr. Zomboss said Plant Food is made out of zombies which is somewhat true as zombies drop Plant Food.
Chomper is referenced after the battle, even though it did not appear in the game at the time of Dark Ages - Part 2's release.
This is the first of two Zomboss fights where the player always gets a boosted plant (in this case Magnet-shroom) and a premium plant (in this case Pea-nut) at one point. The second is Big Wave Beach - Day 32 (With Lily Pad as the boosted plant and Homing Thistle as the premium plant.).
This is the only Zomboss fight where the player faces him on Level 20, instead of Level 25 or higher.
Additionally, this boss is the first creation to neither appear to be quadrupedal nor be fully visible.
This is the first Zombot who has the charge attack does not include the creation performing a running dash across two adjacent rows.
The charge attack is also unique for disabling affected tiles (lasts for a few seconds) so plants cannot be placed there for a short time.
The player can only have five Kernel-pults, ten Fume-shrooms, ten Pea-nuts, ten Puff-shrooms, and one Magnet-shroom on the lawn at a time.
When completing this level for the first time, the trees on the map will be grown.
The Zombot Dark Dragon can kill Dark Ages Gargantuar if the Zombot is in its lane and the Dark Ages Gargantuar is close enough (buttered by Kernel-pult early or pushed back by Fume-shroom's Plant Food effect).
