The Snail Whistle first appears in Volume 2 as a mysterious artifact capable of producing an eerie low-tide sound when blown. Its role expands beyond a simple sound-producing object as its strange patterns and acoustic properties become linked to deeper mystical phenomena within the series. The artifact's evolution reflects the growing complexity of the world's supernatural systems, transforming from a curious item into something potentially connected to larger cosmic forces.
