Effects[]

Upon use, Isaac holds a poison Bomb which can be thrown in the cardinal directions and explodes on impact.
- The bomb can fly across the room for a range before falling to the ground and explode, a distance equal to that of Isaac's tears' if the player's current range is 9.50.
- The explosion deals a flat 50 + Isaac's tear damage and poisons affected enemies.
- The explosion deals a flat 185 + Isaac's tear damage and leaves behind a gas cloud that poisons affected enemies. The poison cloud deals 5 damage.
- The poison deals 6 or 8 points of damage over time.
- The poison deals 3 times Isaac's tear damage over time.
- It will bounce off walls slightly before exploding on the floor.
This item belongs to the Bob set. Collecting three items from this set will transform Isaac into Bob.

Notes[]

This item can drop from Sloth.
Bob's Rotten Head is affected by many tear modifiers and some bomb modifiers. Notable exceptions and precautions are listed below.
Bob's Rotten Head cannot directly impact Beggars, Slot Machines, or Blood Donation Machines, just passing through, but can destroy them with the blast damage if it impacts anything nearby and open Secret Rooms, Super Secret Rooms, or destroy rocks like any other bomb.
Certain interactions require Flat Stone to be effective or work.

Interactions[]

Bob's Bladder / Bob's Curse / Bobby-Bomb / Bomber Boy / Fast Bombs / Scatter Bombs / Mr. Mega: No effect.
Blood Bombs: Bob's Rotten Head leaves a pool of red creep on the ground after each explosion.
Book of Virtues: Spawns wisps in the middle ring. The wisps shoot arcing green tears with decreased range, with a 7.5% chance of firing an explosive, poisonous tear.
Car Battery: No effect.
Continuum: Bob's Rotten Head can now travel through walls and appear out of the opposite wall, similar to a portal-type mechanic.
- No longer travels through the wall; instead he bounces off it, like with Rubber Cement, and then travels for the rest of its duration and then explodes.
Holy Light: Has a chance to throw a Holy Light head that spawns a damaging beam of light dealing (4x) 3x the explosion damage when it hits an enemy.
The Parasite: Causes two smaller tears to appear that explodes for half the damage of the head. Tears do not look like the normal head.
Cricket's Body: Spawns four smaller heads that explodes for half the damage of the bigger one.
Explosivo / Sticky Bombs: If Bob's Rotten Head sticks to an enemy (sometimes with Explosivo, always with Sticky Bombs), the explosion is delayed but will deal 110 damage.
- No longer sticks to enemies.
Flat Stone: Will cause Bob's Rotten Head to bounce once, exploding twice and leaving two gas clouds.
Fire Mind: Creates fire when the head lands.
Godhead: Creates a Godhead aura around the head when thrown.
Haemolacria: When the head lands, tears are fired.
Rubber Cement: Causes the head to bounce off of rocks and walls.
Sacred Heart: Homing effect is applied.
Tiny Planet: When used, Bob's Rotten Head will orbit the player similar to a tear.
Trisagion: Explodes multiple times before reaching its target, dealing explosive damage and knockback to Isaac.
- Shoots a white blast of light instead of the head that pierces through enemies, and causing explosions when it contacts an enemy (if not killing it at the first tick), an obstacle, or when it runs out of range. One tick of the beam deals 33% of Bob's Rotten Head's damage to enemies, but the resulting explosion every tick deals full damage.
Uranus: Enemies are frozen when dying to Bob's Rotten Head.
Worm Trinkets: Bob's Rotten Head is affected by trinkets like Hook Worm and Wiggle Worm the same way tears are.
