Zombot Sphinx-inator

The Zombot Sphinx-inator is the boss of Ancient Egypt in Plants vs. Zombies 2: It's About Time. It is controlled by Dr. Zomboss, and is battled in Ancient Egypt Day 25.

The boss battle is a conveyor-belt level, which gives the player Bloomerangs, Cabbage-pults, Repeaters, Wall-nuts, Bonk Choys, Iceberg Lettuces, and Grave Busters. The Sphinx-inator can send out all zombies from Ancient Egypt, except the Flag Mummy Zombie, Ra Zombie and Camel Zombies. It takes up a 2 by 2 area at the right side of the lawn, and jumps into different rows occasionally. It can only send out zombies in two rows at a time, but it can only be attacked in the two rows it occupies at any one time. Unlike the original Zombot, the Sphinx-inator can be attacked at all times.

Almanac Entry
TOUGHNESS:   Undying

SPEED: Hungry

The destroyer of plants from the ancient sands.

Special:   missile attack can create tombstones

To add that extra bit of wickedness to the Sphinx-inator Dr. Zomboss chiseled his creation from the stonework of cursed tombs. You should not take this instance of reuse and recycle to mean he's going green. The only thing green about him is his tongue.

Overview
The Zombot Sphinx-inator has an estimated absorption of 1,000 normal damage shots, and its appearance changes at 334 normal damage shots and 667 normal damage shots, and 1,000 normal damage shots before surrendering.

Attacks
The Zombot Sphinx-inator randomly performs one of the following actions:
 * Warps in zombies:
 * Only in first phase:
 * Tomb Raiser Zombie
 * Only in second phase:
 * Imp Mummy
 * Mummified Gargantuar
 * Only in third phase:
 * Pharaoh Zombie
 * Explorer Zombie
 * The Zombot Sphinx-inator will summon Mummy Zombies, Conehead Mummies and Buckethead Mummies in all phases
 * A target will appear on a random space, and the Sphinx-inator will shoot a missile at that space, destroying any plant on it, attempting to create two Tombstones nearby.
 * The Sphinx-inator will tap its front two legs on the ground, step back, and then charge forwards, destroying all plants and zombies in two rows. It will then stop short of the Lawn Mowers, and jump back to the rightmost column.
 * It is possible to stun it with the Plant Food effects of Repeaters, Bloomerangs, Bonk Choys or Cabbage-pults or a single Squash when it uses this attack, preventing the attack from destroying two whole rows.
 * It is also possible to do this by making it hit an armoured Wall-nut, but this is not recommended, as the Zombot Sphinx-inator will not be damaged if it hits an armoured Wall-nut.

Strategies
See Ancient Egypt - Day 25.

Trivia

 * Its almanac entry says the only thing green about Dr. Zomboss is his tongue, which is incorrect because his body is green, and if one looks closely, his tongue is in a normal pinkish hue.
 * This fight was added in the 1.9 update for Plants vs. Zombies 2: It's About Time.
 * Before the fight, Dr. Zomboss suspected our Crazy Dave is a brain-eater like them because he thinks the meat inside Dave's taco was BRAIN meat.
 * Dr. Zomboss calls Crazy Dave "David".
 * This name was first used in Plants vs. Zombies Adventures.
 * If the player waits long enough in the level selection screen, Dr. Zomboss is seen brushing his teeth.
 * The robot has one eye, like a cyclops.
 * When Dr. Zomboss is defeated, the players are awarded with the Ancient Egypt Trophy.
 * Also, after you received the trophy, Crazy Dave pops out and confirmed there was no meat inside the taco. Dr. Zomboss says " Well, that just leaves more brain for us later" and claimed he will return for a real pay-back. He then teleports away with what's left of Zombot Sphinx-inator.
 * Although it says in its almanac that the Zombot Sphinx-inator's toughness is "undying," it is possible to defeat it legitimately.
 * This is probably to emphasize its power and extremely high toughness.
 * When the Zombot Sphinx-inator is frozen and about to shoot a missile, it will be blue, but when it comes back from the top, it is no longer frozen.
 * If an Iceberg Lettuce is hit with a missile, the Iceberg Lettuce will somehow freeze the Zombot Sphinx-inator. This was fixed in the 2.3 update.
 * In the Chinese version of Plants vs. Zombies 2: It's About Time there is a minigame in where the player has to fight the Zombot Sphinx-inator as a Last Stand level.
 * The missiles launch Tomb Raiser Zombie's bones on impact.
 * In the Chinese Version, battling this Zombot can have the following:
 * A conveyor-belt manner which is the typical type. A Last Stand without the aid of Sun-producing plants, and lastly a Last Stand manner with the aid of sun-producing plants but the Zombot Sphinx-inator will have three phases of health.
 * In this battle, Bonk Choys, Wall-nuts, and Grave Busters are limited. The player can only have five Bonk Choys and Wall-nuts and two Grave Busters at a time.
