Disambig.png This article is about the boss. For the enemy, see Gurgling (Enemy).

Gurglings are a boss that can appear:

They each have 60 HP.


The Gurglings spawn as a pair and wander around the room. Each individual Gurgling has one attack in total which is performed independently of the other:

  • Rushes towards the player when aligned in any cardinal direction, leaving behind damaging Red Creep until she has run into a wall.
    • After rushing into a wall, she pauses for a brief moment, and then spawns 0-2 Attack Fly Attack Flies.
    • Her dash can be interrupted if she runs into an Attack Fly.

Champion Versions Needs to be unlocked[]

  • Nothing
  • 2 rocks (1 in top-right and 1 in bottom-left corners)

  • 7 Red Poop Red Poops & 6 pits in the bottom of the room
  • 4 Red Poop Red Poops (2 in top-right and 2 in bottom-left corners, covered with 3 rocks and 1 metal block each)

Bug Bug! Removed in Afterbirth If the player stays close to walls, the Gurglings will not charge.
Bug Bug! If both Gurglings charge at once, only one of the Gurgling's grunting noise file will play.
Bug Bug! Removed in Afterbirth † When fought in the Boss Challenge Room Boss Challenge Room, they will appear in their enemy form rather than their boss form, making them much weaker and lacking a health bar.
Bug Bug! When the Gurglings are slowed and attempt to charge Isaac, they can't move and constantly spawn Attack Flies. Similarly, the "mini-boss" Gurglings attempting the same attack will constantly shoot 6 blood tears.
