YO LISTEN!

Effects

• +1 luck.
• Spawns a familiar that sporadically moves around the room.
• Upon entering a room with a Secret Room/Super Secret Room entrance, tinted rock, or a rock with a Crawl Space underneath, it will fly towards it.
  • If there are multiple secrets, then it will fly from one to the other.
• (Added in Repentance) This item belongs to the Beelzebub set. Collecting three items from this set will transform Isaac into a giant humanoid fly.

Notes

• The familiar will sometimes hover over a pit, poop or empty tile, indicating that an unreachable crawl space has been generated there.
  • Although it might seem intuitive to dig the spot open with We Need to Go Deeper! or (Rune of Ehwaz) Rune of Ehwaz, their chance of spawning a crawl space is independent and not guaranteed to work.
• An extra crawl space that is added by (Stud Finder) Stud Finder won't be identified by the familiar.
