Dark Arts & Crafts is an object debuted in the episode, Poppet Master.
Description[]
Before the dust is cleared off, it looks like an ordinary arts and crafts book, most notably with an entire chapter on doll making, but once the full cover is exposed and the spell-laced descriptions are read, it is clear that it is really a book on black magic, and the dolls created from them have the power to control others to the holders will.
Trivia[]
The dolls made from this book are referred to as "witches poppets", even though they are technically voodoo dolls.
