Future sunglasses

Future Sunglasses are glasses that some zombies wear when the Code "future" is typed, while Plants vs. Zombies is being played. They are worn by regular zombies, Flag Zombies, Conehead Zombies, Buckethead Zombies, Screen Door Zombiesand Ducky Tube Zombies (all kinds) while the code is active.

They have no effect on the game, although if a zombie wearing the glasses bites a Garlic, it will instantly switch lanes, but a zombie without glasses will bite the Garlic, make a face, then switch lanes.

Trivia

 * According to the Tree of Wisdom, the zombies that wear these glasses are from the future.
 * In DS version Pool levels, ravens drop these sunglasses to zombies' heads.
