Ancient Egypt - Ultimate Challenge


 * For the international version of this level, see Ancient Egypt - Day 25.

Difficulty

 * Different with the international version of this level, the Zombot only takes a 1x2 area to stand, and only summons Mummy Zombies and Conehead Mummies. But its chance to fire missiles is higher, so the player could end up with weak zombies coming towards the house but also with tons of tombstones covering up all of the lawn. Other than these tombstones, this is just a duplicate of Day 1.

Strategy

 * It is recommended to keep one Iceberg Lettuce, one Grave Buster, and one Plant Food at all times. This way, you can quickly remove tombstones that show up in bad places, and you can use Plant Food to counteract the Sphinx-inator's charge attack.
 * Use Plant Food on Bloomerangs, Repeaters or Bonk Choys to clear out rows of tombstones.
 * The Zombot Sphinx-inator will always send weak zombies. Conehead Mummies are not sent until phase two (when one-third of its health is gone). Try to take care all of them with a Bonk Choy or a Repeater fed with Plant Food in between the zombies. Do not plant the Bonk Choy in the middle of a Zombie stack or it will be eaten, unless if you can quickly put a Plant Food on the Bonk Choy which is in the middle of a Zombie stack, it can kill all the zombies with ease.
 * Never waste Plant Food. If one appears, and you still have Plant Food, use one if it is needed, and then pick up the additional Plant Food.
 * In lanes where you are about to lose, place several plants there, so the Zombot Sphinx-inator will kill the zombies later.
 * Try to use Iceberg Lettuce when the Zombot Sphinx-inator is at a lane with many strong plants. It cannot freeze the Zombot Sphinx-inator, however, but rather just slow it down. (Note: Use it at the ninth column, as if you plant at the eighth column, it'll be squashed by Zombot)
 * When its target locks onto a plant, use Plant Food on that plant to keep the missile from destroying that plant when needed.
 * For Bloomerangs and Cabbage-pults, only use Plant Foods when the missile almost lands on it because they have a short Plant Food duration.
 * Keep Bonk Choys up at front and use Plant Food on them when Zomboss is close.
 * If Zomboss charges down a lane which are full of zombies, make sure to give plant food to the plant closest to the zombies when the Zombot is right next to that plant. If done correctly, it will stall Zomboss just as he finishes trampling the zombies.
 * If you have a Repeater on the lane which Zomboss is where there are no tombstones and you have a Plant Food, use the Plant Food before Zomboss leaves the lane. This can deal a lot of damage to Zomboss.
