If you were a Zombie you might know that you cannot drink from normal mugs. That's right Zombies have to drink from special heat changing Zombie Mugs. We don't know why, it's just true, ask any Zombie.
Just add hot water to the Zombie Mug and what appeared to be a blank mug now has a picture of a fairly gruesome Zombie. Just right a a lovely cup of Zombie tea in the afternoon.
Not dishwasher or microwave safe.
