Monster Lady

The Monster Lady is a character in The Minish Cap. She takes over the house of the poet, Percy, while he was away for a long journey. When Link enters the poet's house, the strange woman asks him to not turn on the lights since the darkness warms her soul. Turning on both torches with the lantern reveals the woman is actually a Moblin, asking Link to not tell anyone and gives him 50 Rupees.

Trivia

 * The Moblin inside Percy's house is a direct reference to the original, in which Link could find Moblins hidden in secret caves with two flames at their side, often rewarding the young hero with Rupees and uttering the famous phrase: "IT'S A SECRET TO EVERYBODY."
 * The act of using light to reveal the woman's true form as a monster is also a reference to Blind the Thief from.
