Binding of Isaac: Rebirth Wiki
This article is about the boss. For the enemy, see Gurgling (Enemy).

Gurglings are a boss that can appear:

They each have (in Rebirth) 90 HP / (except in Rebirth) 60 HP.

Behavior[ | ]

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 they have run into a wall.
    • After rushing into a wall, they pause for a brief moment, and then spawn 0-2 Attack FlyAttack Flies.
    • Their dash can be interrupted if they run into an Attack Fly.

Champion Versions Needs to be unlocked[ | ]

(except in Rebirth) Black: Gurglings spawn Troll BombTroll Bombs at regular intervals instead of Red Creep when rushing towards the player. They take only 5 damage from their own bombs. They don't spawn any Attack Flies.
  • While petrified, the Gurglings take full damage from own bombs.
(except in Rebirth) Yellow: Three Gurglings will appear instead of two. They are faster but do not leave any Creep. They don't spawn any Attack Flies.

Bugs[ | ]

Bug Bug! (in Rebirth) 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! (in Rebirth and Afterbirth) When fought in the Boss Challenge RoomBoss 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.
