Frowning Gapers look identical to regular Gapers, but have empty eye sockets that appear closed before they get close to Isaac.
They first appear with their eyes closed and will start following Isaac. Once they get close to him, their eyes opened. Frowning Gapers move quicker than regular Gapers and spawn Pacers and Gushers more often upon death.
- They appear in the original game.
- Horfs have the same sprite as the awoken Frowning Gaper's head.
