Behavior[edit | edit source]
Phase 1[edit | edit source]
- Hops in place and then immediately performs a slide a with slight shift toward Isaac, firing projectiles in both perpendicular directions as it moves and leaving trails of explosive gas.
- Colostomia performs this attack 1 to 3 times in a row
- The direction of the slide depends on the player's position, which can be used to trick Colostomia into moving in specific directions.
- The vertical slide is usually easier to avoid, as the boss spawns less bullets and they also travel less distance.
- Throws a Butt Bomb toward Isaac that can ignite the gases, which kill over time, around to cause a chain explosion.
- This is always its first attack when spawning.
- Unlike Isaac's Butt Bombs, these do not create a damaging cloud.
Phase 2[edit | edit source]
After taking enough damage, the bag containing Colostomia explodes and leaves it adhering to the floor.
- Jumps to another nearby location, firing 8 projectiles in a radial burst and creating a puddle of harmful brown creep when it lands.
- Spews two Butt Bombs at Isaac.
- Farts, creating a ring of explosive gas around its location

Trivia[edit | edit source]
- Colostomia is based on a Colostomy bag, a removable, disposable bag that attaches to the exterior opening of a colostomy to permit sanitary collection and disposal of bodily wastes.
