Mummified Duck

At any time, you may trick-or-treat a player you haven't trick-or-treated before.
Trick: Your opponent must tell you the color of their card. If it's green, they must scream I want my mummy! and give you two pieces of candy. If it's red, you die and must exchange give this card to a moderator in exchange for a Skeleduck card. If it's neither, nothing happens.
