Harrowing Holiday Harpoon Harp Trap

An enchanting melody plays on this fantastical harp, a tune so old that only Draconic mice would know of its origins. Once an intrigued mouse comes near, it triggers the continuation of the tune, luring the mouse even closer. During the crescendo, the inconspicuous dragon ornament takes aim at the enthralled concertgoer, then it fires its harpoon at the climax of the song, while the mouse is in a deep trance.
