Nightmarish Bird Whistle

The Nightmarish Bird Whistle is a craftable Item exclusive to the Hamlet DLC. It is found in the Magic Tab, requires a Bird Whistle and two Dark Tatters to craft, and a Hogus Porkusator to prototype.
Using the Nightmarish Bird Whistle prevents the BFB from spawning naturally in the world. Once the Nightmarish Bird Whistle has been played, the BFB will only spawn in the future if it is called by the original Bird Whistle.
== Tips ==
* Using the Nightmarish Bird Whistle can be helpful to prevent the periodic interruptions and base evacuations that the natural spawning of the BFB can cause.
* Note that this item will only affect future spawns; it will not cancel a naturally spawning BFB that is already currently descending.
* Because the BFB can still be called using the Bird Whistle, Dung Piles will remain renewable, and the player will still have access to the Pinacle if they had not visited it before using the Nightmarish Bird Whistle.
* As the Ancient Herald will only drop five Dark Tatters when it is defeated, the player may wish to remain in the Aporkalypse long enough to defeat it twice if they wish to have enough to craft both the Vortex Cloak and Nightmarish Bird Whistle.
