The Yeti Zombie in Plants vs. Zombies: Replanted is a rare, elusive enemy that never appears during your first run through Adventure Mode. To encounter this creature, you must progress to your second playthrough—known as Adventure Mode Plus—or reach higher waves in Survival Endless. Encountering the Yeti Zombie unlocks the Cryptozombologist achievement and gives you a chance to claim four diamonds upon defeating it.
Yeti Zombie Overview and Stats
The Zombie Yeti functions differently from regular lawn intruders. Instead of marching steadily into your house to eat brains, it ventures a short distance onto the screen, pauses, and then turns around to flee off the right edge of the lawn.

Where to Find the Yeti Zombie
There are two primary ways to encounter the Yeti Zombie in Plants vs. Zombies: Replanted.
Method 1: Adventure Mode Plus (Level 4-10)
The most reliable way to find the Yeti Zombie is by replaying Adventure Mode:
- Complete Adventure Mode once: Finish Level 5-10 and defeat Dr. Zomboss to earn the Home Lawn Security achievement. This unlocks Adventure Mode Plus (Adventure+).
- Advance to Stage 4: Play through the daytime, nighttime, and pool stages until you reach the Fog area.
- Reach Level 4-10: This is the thunderstorm conveyor-belt level where the screen flashes between pitch black and lightning-illuminated views.
- Spot the Yeti Zombie: In Adventure Plus, the Yeti Zombie is scripted to appear on Level 4-10, usually arriving just before or during the second major wave of zombies.
If you finish Level 4-10 and fail to spot him, do not collect the coin bag at the end of the level. Instead, pause the game and select "Restart Level" to try the encounter again.
Method 2: Survival Endless
The Yeti Zombie can also appear randomly in Survival Endless. In this mode:
- The Yeti Zombie can spawn across various flags once higher wave counts begin.
- Players documenting Survival Endless runs report seeing the Yeti show up in fog or pool layouts, occasionally appearing around Wave 20 or later flags alongside Gargantuars and Zombonis.
- While this method does not guarantee an appearance at a specific timestamp, it allows you to encounter multiple Yeti Zombies over long endurance sessions to farm diamonds.
How to Defeat the Yeti Zombie
Because the Yeti Zombie turns around and retreats quickly (traversing one tile every 2.1 seconds while fleeing), standard peashooters placed in back rows often lack the burst damage needed to eliminate it before it escapes.
- Use Instant-Kill Plants: High-damage explosives like Cherry Bombs, Jalapenos, Doom-shrooms, or Squashes can instantly wipe out large portions of the Yeti's 1,350 total health pool.
- Slow Down the Retreat: Use Ice-shrooms or Winter Melons to freeze and slow the Yeti down. Freezing gives your offensive lineup sufficient time to deplete its health before it walks off the right side of the lawn.
- Conveyor-Belt Strategy (Level 4-10): On Level 4-10, you are limited to the plants provided on the belt. Save heavy hitters, such as Cacti or Starfruit, and deploy defensive stalls or burst plants immediately when the Yeti enters the lane.
Taking him down causes him to drop four diamonds, giving you an immediate boost of 4,000 coins toward purchasing seed slots or shop upgrades from Crazy Dave.
Unlocking the Cryptozombologist Achievement
The Cryptozombologist achievement (listed in official Steam and console versions as discovering the "Yeti Zombie" or "Top Secret Zombie") triggers the moment the Yeti appears on the screen.
You do not need to successfully kill the Yeti Zombie to pop the achievement; registering its presence on your lawn is enough to satisfy the unlock condition. However, eliminating it before it runs away is strongly recommended due to the high diamond payout.
