Gaping Maws are a type of regular Stone Grimaces added to The Binding of Isaac: Rebirth and first encountered in Chapter 2.
They were occasionally surrounded by spikes and can suck Isaac towards it, along with warping Isaac's tears and every enemies' tear paths. It does not fire any shots like other types but instead functions as an obstacle.
- Gaping Maws, along with other types, can be destroyed using the Chaos Card. However, they will respawn upon leaving and re-entering the room they were in.
- The words "gaping maw" is actually used to describe a monster from video games and movies by their mouths.
