Promotional zombies

Throughout the Plants vs. Zombies series, many zombies have been seen which are promotional material or small cameos in-game. These zombies were never intended to appear within the games, and they most likely never will.

Vampire Imp


Vampire Imp is a zombie that only appears in the YouTube video Stop Zombie Mouth! It is behind two graves that say Hal Itosis and Gingi Vitis, two mouth disorders caused by not brushing teeth (see Wikipedia articles for halitosis and gingivitis). It is an Imp with a vampire's cape, but not much is seen because it is hiding behind the graves.

Trivia

 * This zombie was most likely the inspiration for the Vimpire from Plants vs. Zombies Heroes.

Zombie Queens
Zombie Queens appear in the PopCap advertisements. So far, only three are seen, and since the ads were meant to promote the first game, it is likely no more will appear. The first is a somewhat obese zombie with yellowish skin, wearing a tiara, messy lipstick, and a pink bow in its hair. It has somewhat the resemblance of Catapult Zombie The second is not fully seen, as only a closeup of its chest is in the advertisement, but it has more green skin, a brown cloak with fancy patterns, and red nail polish. The final one has grayish-green skin similar to other zombies in the series, is fairly skinny, has long hair topped with a crown, and a long red dress.

Trivia

 * They are a parody of the controversial Evony ads, which frequently used misleading advertisements to attempt to sell their game.
 * Aside from zombies created in Zombatar, these are the only zombies to have skin tones different from other zombies.

Zombie Worm


Zombie Worm is a zombified version of the character Lex from the PopCap game Bookworm with a zombie head. It appears next to Lex when the player is scrolling down on the achievements area on the way to the Chinese Zombies. It is one of the four zombies seen going down the achievements page, along with the three Chinese Zombies.

Sunflower Zombie
Sunflower Zombie is a zombie that appears in the Xbox 360 and PlayStation 3 versions of Plants vs. Zombies. The only thing that it serves is for customizing the player's house and after getting it (by earning the Soil Your Plants achievement) and puts it in the player's house, it will only move and act as a normal Sunflower. It is first seen in the Xbox 360 Trailer.

Overview
Sunflower Zombie is just a Sunflower in a Flower Pot with a zombie or an Imp head. It's a decorative object that appears on the lawn and it will be just "dancing" as a normal Sunflower does. It has also an official artwork as seen in the official PopCap Games facebook page. The artwork was posted on May 2, 2012.

Trivia

 * Not like any other zombies combined with plants, Sunflower Zombie does not have a full zombie body with a plant head but has the full Sunflower body with an Imp or zombie head.
 * However, it has a regular zombie head on the Plants vs. Zombies Facebook page and some of its petals are missing.
 * Besides the zombies from ZomBotany, the Sunflower Zombie is the only zombie that is both a zombie and a plant.
