Zombie Yeti

The Zombie Yeti is the last Zombie that the player will encounter, as its first appearance is Dark Stormy Night (level 4-10, the second time Adventure Mode is played). The Zombie Yeti is based on the cryptid Abominable Snowman (AKA: Yeti) that lives in the Himalayas.

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
It takes 46 Normal Damage shots. Appearance changes upon 23 Normal Damage shots before dying at 46 Normal Damage shots. Zombie Yetis drop 5 diamonds when first encountered. On every other encounter after that, only 4 diamonds are dropped. It runs away after a short while, so kill it quickly!

Strategy
Just do whatever you do to kill Buckethead Zombies (obviously besides using Magnet-shrooms). If it tries to run away, it can be stopped by planting a Wall-nut or another defensive plant in its path such as the 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 it or an Instant Kill plant like Jalapeno, Squash or Cherry Bomb can be used. Also remember to watch out for it in Last Stand

Gold Farming
One technique is to repeatedly attempt Level 4-10 (once completing it once), the only level in the game where the Zombie Yeti consistently appears. Because the Zombie Yeti, when defeated, yields four diamonds ($4000), the gold farming application is obvious. Do note, however, that 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 it the first time. To be able to keep replaying the level, it is of utmost importance 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 Game of the Year edition does not allow farming of this zombie, because you can't Yeti farm by restarting level 4-10. Although if you restart and you don't kill him, it will still appear. But if you have both versions, move the saved data from Game of the Year PC version to the old one, and do Gold Farming there.

The other one is use this trick (we can get $200,000 with 5000 suns)
