Zombologist is an achievement that can be earned in the iOS, and PlayStation Vita versions of Plants vs. Zombies. It is worth 25 points on Game Center. This achievement is earned by finding the Zombie Yeti. It is the equivalent of the Cryptozombologist achievement available through the Steam Game of The Year edition.
Zombologist is a portmanteau of "zombie," referring to the Zombie Yeti and "zoologist", a person who studies the animal kingdom.
- Its manner is similar to the Sasquashed! achievement in Plants vs. Zombies 2, however, it is required to destroy the Yeti Zombie upon finding it to complete the achievement.
