Bulbs are fly-based enemies added in The Binding of Isaac: Repentance. They fly in erratic, right-angled motions.
If Isaac has an active item with any amount of charges (this includes timed recharge items), they fly towards him and drain up to 2 charges upon contact, but do not deal damage.
If Isaac does not have an active item, or if his item has no charges, they simply fly randomly and are completely harmless.
Bulbs replace the Greed Gaper in treasure rooms.
Variants[edit | edit source]
Bloodfly[edit | edit source]
Bloodflies are enemies added in The Binding of Isaac: Repentance. Exclusively encountered in Corpse, they behave very similarly to Bulbs in movement but unlike Bulbs, don't drain charges and deal contact damage.
Bloodflies are spawned by Pustules if they are destroyed after reaching maximum size. Bloodflies chase Isaac, and, upon death, shoot 4 blood shots in the cardinal directions.
Trivia[edit | edit source]
- Bulbs are one of the few enemies not to deal contact damage, along with Black Flies and Mulligans (unless they are Champions).
