Bob's Brain is a passive item.

Effects

  • Spawns a familiar that can be fired towards enemies as a projectile.
    • Template:NoDLC Bob's Brain is fired directly from where Isaac is standing.
    • Template:Afterbirth: Bob's Brain is fired directly from where it is located in the chain of familiars behind Isaac, making aiming it slightly more difficult.
  • If it hits an enemy, it explodes, damaging and poisoning monsters.
    • The explosion deals 60 damage and the poison deals double Isaac's damage over time.
  • The explosion can hurt Isaac, dealing a full heart of damage.
    • This can make picking up the item a risky choice, as Bob's Brain will always fire, regardless of whether or not Isaac will be caught in the explosion.
  • Once it explodes, it takes a few seconds to re-appear.
  • Error: Error: No Book of Belial interaction found for "Bob's Brain"

  • Bob's Brain only explodes when hitting an enemy, and does not explode upon hitting a fire, poop, or wall.
  • Bob's Brain never launches immediately upon entering a room unless a tear-firing key is released and pressed again, or until several seconds have passed.

    • Multiple copies of Bob's Brain will float in the same spot in the familiar line.
