Trivia

 * In the Xbox Live Arcade version, this achievement is called "Master of Morticulture", not "Morticulturalist".
 * This achievement is similar to the Nintendo DS achievement "Book Learner". However, Book Learner requires encountering the Zombie Yeti, which means that the player has to play Adventure Mode at least twice.
 * The old image for this Achievement is a yellow background with a Sunflower winking.
 * The Sunflower in the song Zombies on Your Lawn also winks at the end.
 * The new image is a reference to the phrase "green thumb", which means a natural skill for gardening.
 * The hand on the new image only has 4 fingers and the thumb turns green, just like a zombie.
 * You must complete Adventure Mode mode at least once, since the Winter Melon, Cob Cannon and the Imitater can only be obtained after completing Adventure Mode once.
 * 'Morticulturalist' is a combination of the word "horticulture," which means gardening, and words that contain the latin root "morti" means to have a relation to death or the emotions relating to it.
 * The lawn ornament in the Xbox Live Arcade version is a garden gnome, with Crazy Dave's face, holding a Peashooter.
