Theodor Seuss Geisel's Grinch Santa Hat

Origins
Theodor Seuss Geisel, better known as Dr. Seuss, was a famous writer and illustrator of his own children’s books. Many were simple, short stories that rhymed. Some of his stories include Green Eggs and Ham, The Cat in the Hat, The Lorax and Horton Hears a Who. The hat came from his writing of How the Grinch Stole Christmas, a Christmas themed tale.

Effects
Causes the wearer to become a kleptomaniac and get extremely attracted to anything that is red, green, or white, as well as causing the person to become hateful to anything festive. Also renders the wearer invisible when they enter someone else's home. The effects of the hat can be broken when the hat is taken off, or when a child under the age of 6 catches the person in the act (they are the only people able to see the person wearing the hat while they are in someone else's home) and asks them what they are doing. A way to tell if a person is under the influence of the hat is by hugging them, as the hat gives them a spiky texture, making them become "as cuddly as a cactus".

People under the influence of the hat will also try to avoid places where crocodiles are kept, especially if the crocodile is seasick. Also, if a person is separated from the hat too quickly without it being neutralized, their heart would grow three times larger and explode.
