Binding of Isaac: Rebirth Wiki

A Stone Grimace is an invincible stationary statue with the shape of a head with a wide-open mouth and hollow eyes. Stone Grimaces will sporadically spit a Red bullet in Isaac's direction until the room is cleared by killing regular enemies, or by pressing Pressure PlatePressure Plates. When the room is cleared, the Stone Grimace closes its eyes and mouth.

Variations[ | ]

Vomit Grimace[ | ]

The Vomit Grimace fires an explosive Collectible Ipecac iconIpecac-like shot. Like Stone Grimaces, Vomit Grimaces will stop firing at Isaac when the room is cleared.

Triple Grimace[ | ]

(in Repentance)

The Triple Grimace fires a triple shot. Like Stone Grimaces, Triple Grimaces will stop firing at Isaac when the room is cleared.

Gaping Maw[ | ]

The Gaping Maw sucks Isaac towards it, along with warping Isaac's and any enemies' bullet paths. It does not fire any shots and simply functions as an obstacle, and is often surrounded by spikes. (except in Rebirth) They can, however, be deactivated by Pressure PlatePressure Plates.

Notes[ | ]

Broken Gaping Maw[ | ]

A broken variant of the Gaping Maw. It alternates between active and inactive every four seconds, but it has a much stronger attraction power. (except in Rebirth) Just like regular Gaping Maws, they can be deactivated by Pressure PlatePressure Plates. Prior to Afterbirth+ Booster Pack 5, only one room in the game contained Broken Gaping Maws.

Constant Stone Shooter[ | ]

Constant Stone Shooters, sometimes referred to as Turret Grimaces, constantly fire bullets in a fixed direction, and do not stop firing even after the room is cleared. (except in Rebirth) The exceptions are rooms with Pressure PlatePressure Plates, which deactivate them once they are all pressed.

Cross Stone Shooter[ | ]

(in Afterbirth † and Repentance)

Cross Stone Shooters were added in Booster Pack #4.

The Cross Stone Shooter, sometimes referred to as Cross Grimace, constantly fires bullets in four directions, alternating between cardinal and diagonal directions. If the room has to be cleared, whether by killing enemies or by pressing Pressure PlatePressure Plates, then Cross Grimaces will deactivate upon the room's completion like a regular Grimace. However, if the room is purely trap based and does not present an objective to complete, then Cross Grimaces will continue shooting indefinitely.

Brimstone Head[ | ]

Found in (in Repentance)GehennaGehenna and SheolSheol, the Brimstone Head, sometimes referred to as Brimstone Grimace, periodically shoots Collectible Brimstone iconBrimstone lasers and does not stop firing even after the room is cleared. (except in Rebirth) The exception is pressing all Pressure PlatePressure Plates, which deactivates them.

Stone Eye[ | ]

The Stone Eye resembles the Bloodshot EyeBloodshot Eye. It constantly rotates in a clockwise circle and shoots a flickering Collectible Technology iconTechnology laser. It stops firing after the room is cleared. Unlike any other Stone Grimace variants, the Stone Eye appears to despawn when the room is cleared, exited, and then re-entered.

Bomb Grimace[ | ]

(in Repentance)

The Bomb Grimace is a unique Stone Grimace in that its only purpose is to keep a single Throwable BombThrowable Bomb spawned. A few seconds after Isaac takes the bomb, it will spawn another.

If it is destroyed with an instant-death attack such as Collectible Euthanasia iconEuthanasia or Collectible Little Horn iconLittle Horn, it spawns 10 throwable bombs.

Always spawns during the battle of Boss Tuff Twins ingameTuff Twins and Boss The Shell ingameThe Shell.

Quake Grimace[ | ]

(in Repentance)

The Quake Grimace fires a line of rocks in one direction upon landing every 3 seconds. In most cases, even after the room is cleared of vulnerable enemies, they will continue this behavior. However, they can be deactivated from Pressure PlatePressure Plates.

If a Secret RoomSecret Room or a Super Secret RoomSuper Secret Room is placed in the path of their attack, the attack will break the wall and open the entrance.

Notes[ | ]

  • These monsters are impassable, even with flight.
  • These monsters can be destroyed using Chaos CardChaos Card, (in Afterbirth † and Repentance)Collectible Little Horn iconLittle Horn and (in Afterbirth † and Repentance)Collectible Euthanasia iconEuthanasia, though they will respawn upon leaving and re-entering the room they were in.
  • With Collectible Infestation 2 iconInfestation 2, killing Stone Grimaces creates a Blue Spider, allowing blue spiders to be farmed by leaving and re-entering the room.
  • Collectible Fire Mind iconFire Mind tears that hit these monsters can still cause explosions.
  • (except in Rebirth) Hitting Grimaces increases the Collectible Dead Eye iconDead Eye damage multiplier.
  • (in Afterbirth † and Repentance) If an uncleared room has Cross Grimaces, leaving and then re-entering the room by bombing a door will make them stop shooting, making the room easier.
  • (in Repentance) 4 Stone Grimaces can appear in Boss Loki ingameLoki's boss fight.

Trivia[ | ]

  • (in Rebirth and Afterbirth) Stone Grimaces and their variants play their appearance animation for a second before resuming as deactivated in a cleared room if they were deactivated.
    • (in Afterbirth † and Repentance) They now no longer reuse their appear animation in a cleared room when the player re-enters it.
  • If a Constant Stone Shooter is deactivated, it closes its eyes and mouth and stops crying, looking similar to Stone Grimaces upon deactivation. The difference is that deactivated Constant Stone Shooters still have a crack on top of their heads.
  • If a Gaping Maw or Broken Gaping Maw is deactivated, unlike other Grimaces, it doesn’t fully close its eyes. Instead, it closes its eyes only partially and makes a frown.
  • Grimaces will turn green if poisoned.
  • (in Repentance) Boss Great Gideon ingameGreat Gideon is the boss variant of Stone Grimaces.
  • Gaping Maws were going to have fangs, as shown on the Bestiary.
  • (in Repentance)The Bomb Grimace and Quake Grimace first appeared in the Antibirth mod.
    • (in Repentance) Quake Grimaces have substantially different designs compared to their original appearance in Antibirth. Most notably, they are the same size as other Stone Grimaces instead of being twice as large, and they do not have the large gash in their body.
      • Pre-release content of Repentance as well as the "death preview" shows the original version of Quake Grimaces, suggesting this change was made late in development.
    • (in Repentance) Bomb Grimaces are the only Grimaces who don't appear in the bestiary.

Bugs[ | ]

Bug Bug! (except in Repentance) Using the Collectible D10 iconD10 in a room with Stone GrimaceStone Grimaces will turn them invisible. They will not fire, but the space they occupied will prevent Isaac from moving through it like an invisible wall.
