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 Added in Afterbirth Silver Buttons. When the room is cleared, the Stone Grimace closes its eyes and mouth.

Variations

Vomit Grimace

The Vomit Grimace fires an explosive 15►Ipecac Ipecac-like shot. Like Stone Grimaces, Vomit Grimaces will stop firing at Isaac when the room is cleared.

Triple Grimace

Added 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. Added in Afterbirth They can, however, be deactivated by Added in Afterbirth Silver Buttons.

Notes

  • If a Gaping Maw is rerolled with 15►D10 D10, it will always turn into an Oob.

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. Added in Afterbirth Just like regular Gaping Maws, they can be deactivated by Silver Buttons.

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. Added in Afterbirth The exceptions are rooms with Silver Buttons, which deactivate them once they are all pressed.

Cross Stone Shooter

Added in Afterbirth †

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 Silver Buttons, 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 only in Sheol Sheol, the Brimstone Head, sometimes referred to as Brimstone Grimace, periodically shoots 15►Brimstone Brimstone lasers and does not stop firing even after the room is cleared. Added in Afterbirth The exception is pressing all Silver Buttons, which deactivates them.

Stone Eye

The Stone Eye resembles the Bloodshot Eye. It constantly rotates in a clockwise circle and shoots a flickering 15►Technology Technology 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

Added in Repentance

The Bomb Grimace is a unique Stone Grimace in that its only purpose is to keep a single throwable 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 15►Euthanasia Euthanasia or 15►Little Horn Little Horn, it spawns several throwable bombs.

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

Quake Grimace

Added 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 Silver Buttons.

Trivia

  • Removed in 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.
    • Added in Afterbirth † 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.
  • Added in Afterbirth † Previously, Broken Gaping Maws were extremely hard to find. As of Booster Pack #5, they are now more common to find in rooms.
  • Grimaces will turn green if poisoned.
  • Added in Repentance Great Gideon is the boss variant of Stone Grimaces.
  • Gaping Maws were going to have fangs, as shown on the Bestiary. They now can be found surrounded by spikes.
  • Added 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.
