Presumable a fairy tale story. Tales of Boggarts and redcaps that would steal away wicked children in the night. A magical place in the woods. There's a fey market where the fey sell things like dreams and snake-tongues, for “a price I deem good enough.” which could be anything. The Sidhe in the court of the Falling Leaves are known for dressing garishly in bright colors, jesterly.
The Market of the Falling Leaves
Classic tale of be careful what you wish for. See The Boy of the Forest
An old lady who offers sweets to young children. The good children receive what are just general sweet treats. Bad children are grabbed by her claw like hands and taken back to her home. There she cooks them down and makes new treats out of them.
