"Plants vs. Zombies" has 51 types of zombies. Fan's favorite zombie was Dr. Zomboss. The team spent a full month designing the fight against him at the end of the game. Fan liked the Pole Vaulting Zombie due to the likely amusement of its first encounter with the player; he gave an example of a player failing to block it with a Wall-Nut plant, with the zombie jumping over the obstruction. The Newspaper Zombie's first iteration simply read a newspaper, but Werner redrew the character as having become a zombie while reading on the toilet. Fan's brother asked him whether he based the zombie on their father, as he would often read the newspaper on the toilet. Fan said that while he had no such intention, it was his favorite backstory to a zombie. The Dancing Zombie initially resembled Michael Jackson from the music video "Thriller". The zombie was present in the game before his death, but the entertainer's estate objected to its inclusion over a year following his death; PopCap replaced it with a more generic disco-dancing zombie. Many other zombies were cut during development.
