Typing in certain codes or phrases while playing a zombie game will trigger special effects: typing "future" will spawn futuristic zombies, "mustache" will transform zombies' appearances, and "trickedout" may modify lawn mowers; typing "daisies", "dance", or "pinata" will respectively cause zombies to leave daisies, dance, or drop candy when destroyed as the narrator imagines growing to different heights while celebrating with the player.

1. Pssst... here's a tip... type "future" while playing with Zombies to see
zombies from the future!
Typing "mustache" when playing with zombies will bring a terrible
transformation to the undead!
If you type "trickedout", don't be surprised if you see something wacky
happen to your Lawn Mowers!
Hey, I'm 100 feet tall! Celebrate with me by typing "daisies" to get the
zombies to leave tiny daisies behind when they die.
Whoa! I'm 500 feet tall! This calls for some dancing! Type "dance" to get
the zombies to boogie on down!
WOW! I'm 1000 feet tall! Celebrate with me by typing "pinata" to make
zombies spit out candy when destroyed!
