Put it at the start of the boss encounter, before the reveal, then follow the attack with WTF Boom and close a failed run with Womp Womp Fail Sound for a clear rise and fall.

A brief Terraria cue built around a low, unsettling tone that signals a boss is about to arrive, a moment players often link to the Eye of Cthulhu after dark. It makes a listener feel suddenly on edge, as if an easy scene has turned into a fight they are not ready for. The cue comes from Terraria, the sandbox action-adventure game released by Re-Logic in 2011.
