Pooters (吸虫びん Kyūchū bin) are bloated flies commonly found in 1-3 Chapters.
They resemble closely to Black Flies with visible beady eyes and a bloated-looking abdomen.
Pooters move around the room randomly, instead of following Isaac. They fire a single blood shot at Isaac when he gets in their line of sight. Like Black Flies, they cannot deal a contact damage to Isaac.
- They can be spawned by The Wretched, Gurdy, Famine, The Duke of Flies, Mulligans, Swarmers, Hives and Mom.
- They appear in the original game.
- The word "Pooter" is a device used in the collection of insects, crustaceans or other small, fragile organisms, usually for scientific purposes.
