Where
Madhouse only: Main House 1F, Main Hall, birdcage on the small wooden unit (the middle one). The Fandom wiki says it later moves to the Swamp Mine Office (chapter 7); no other source confirms it.
Effect
Stronger version of the Defense Coin (amount unconfirmed).
Verdict
Madhouse has 33 coins for 35 coins' worth of cages: skip this one or the Stabilizer.
