Zombie Yeti is a zombie the player encounters in Plants vs. Zombies. Along with being the 26th zombie encountered in Adventure Mode, he is also the last zombie encountered in the mode, his first appearance is in Level 4-10, but only after Adventure Mode has been completed once so by then the player would have encountered every other zombie. After encountering him for the first time, he can be rarely seen in any other level in the game, but not in the seed selection screen.
Zombie Yeti is based on the Yeti (or the Abominable Snowman) of Nepali folklore. That's where is name comes from, just adding "Zombie" to it, for obvious reasons.
Suburban Almanac entry
Zombie Yeti
A rare and curious creature.
Toughness: high Special: runs away after a short while
Little is known about the Zombie Yeti other than his name, birth date, social security number, educational history, past work experience, and sandwich preference (roast beef and Swiss).
Overview
Zombie Yeti absorbs 1350 damage and his appearance changes upon absorbing 675 damage before dying at 1350 damage. Zombie Yetis drop four diamonds (five on the first time) when killed, but he runs away after a short while, so the player should kill him quickly to earn the diamonds. Note that the diamonds count as money, so the player can obtain 3 diamonds and one bar of chocolate.
Strategies
Be ready to keep an eye at him, as he can appear in any level at any time. However, he is very rare (On iOS, he usually appears between flags 1 and 2 with a 100% chance on Level 4-10's second playthrough). Just do whatever you do to kill Buckethead Zombies (obviously besides using Magnet-shrooms). If he tries to run away, he can be stopped by planting a Wall-nut or another defensive plant in his path such as Pumpkin or Tall-nut.
If that proves insufficient, plants capable of firing backwards such as the Split Pea or Starfruit can be planted in front of him or an instant kill like Jalapeno, Squash, or Cherry Bomb. The cobs from Cob Cannon can also work to one-shot the Zombie Yeti. Potato Mines should not be used as they will need to be planted far ahead from him.
If he appears in Wall-nut Bowling, you can kill him with a single Wall-nut. Slowing him down or freezing him with plants such as Snow Pea or Ice-shroom can buy you some time to kill him before he gets away from the lawn. The Explode-o-nuts that can obtain from watching ads on iOS can also kill instantly.
After completing Level 4-10 for the second time, he can appear in any Mini-game except for Zombiquarium, and a great way to find them is by playing through Survival: Endless, as the high density of zombies means that more attempts of spawning a Zombie Yeti are made and thus your chances of running into him are increased. This can significantly increase your money a lot as if killing large numbers of zombies hasn't already increased it dramatically.
Gold farming
One technique is to repeatedly attempt Level 4-10 (once completing it the second time), the only level in the game where the Zombie Yeti has a 100% chance of appearing. Because the Zombie Yeti yields four diamonds ($4000) when defeated, the gold farming application is obvious. The first time he is killed, he will drop five diamonds. However, if your version of the game has the Quick Play mode on it, Zombie Yeti sightings are just like regular levels, so it is necessary to reach that point in Adventure Mode after defeating him the first time.
To be able to keep replaying the level, it is of extremely imperative that the player does not collect the money bag at the end of the level, or restarts as soon as the Zombie Yeti is killed. The best way to farm efficiently (on IOS) is to watch an ad to get an explosive wall nut, wait until the Zombie Yeti appears, place the wall nut directly on top of the Zombie Yeti, collect the money and then dig up all your plants so the zombies get inside and you have to restart. The Zombie Yeti does not disappear from a level if you save and quit (on IOS) as long as it has been seen in list of zombies appearing in that level.
The Game of the Year Version does not allow farming of this zombie, because Zombie Yeti doesn't respawn again if you restart Level 4-10, although if you restart and you do not kill him, he will still appear. But if you also have the old version, move the saved data from Game of the Year Version to the old one, and do gold farming there.
If the player hypnotizes the Zombie Yeti, he does not drop diamonds, unless he is killed by other zombies.
When the player sees the Zombie Yeti in Wall-nut Bowling, he takes one hit but still leaves the screen when not killed.
Zombie Yeti costume is available on the Xbox Live Marketplace for 320 Microsoft points.
It is possible to encounter Zombie Yeti more than once in a single Survival level, although he will only appear once every flag (or every two flags if in Survival: Hard or Survival: Endless).
Zombie Yeti is one of nine zombies that are unavailable in Versus Mode. This is most likely due to the fact that he does not stay on the yard long enough to do much damage, if any at all. The others being are Backup Dancer, aquatic zombies, Balloon Zombie, Imp and Giga-gargantuar.
In Stop Zombie Mouth!, if one looks closely, Zombie Yeti has three hands.
When a Zombie Yeti bites a Garlic, he will not make a zombie's disgusted face.
On the Plants vs. Zombies Website, the Zombie Yeti and Dr. Zomboss appear in the Almanac, but only as silhouettes.
The Android version has a glitch that Zombie Yeti will never appear outside of level 4-10.
There is another glitch in the iOS version where if the player has updated their game to the newest version, Zombie Yeti on the Almanac (when killed) will be erased into a silhouette. The only way to restore him is to replay Adventure Mode a third time.
