Binding of Isaac: Rebirth Wiki

Larry Jr. is a boss that can appear in the BasementBasement and the (except in Rebirth)Burning BasementBurning Basement.

He has 22 HP per segment.

Behavior[ | ]

The number of individual Larry Jr. bodies that can spawn each fight can vary from 1-4. The most common encounter with Larry Jr. is with 2 bodies.

  • Randomly moves around the room in the cardinal directions, turning when colliding with walls or obstacles.
    • Larry Jr. can change direction if one of his segments is destroyed.
  • Randomly spawns PoopPoop while moving.
    • Colliding with a Poop destroys the Poop and causes Larry Jr. to turn.
  • Larry Jr. segments can be split into smaller copies of the boss as long as the new Larry Jr. segments are longer than 2 pieces.

There is a chance that a GrubGrub can spawn alongside a shorter Larry Jr. (basically replacing a second Larry Jr.) due to its patterns being very similar to the boss.

Champion Versions Needs to be unlocked[ | ]

Blue: Is 15% larger and has 45% more HP (31.9), but moves more slowly and does not leave poop behind. Has shared health between his body segments, meaning that dealing damage to one segment will deal a percentage of the damage to the other segments. This version always drops a Soul HeartSoul Heart when defeated.
Green: Will occasionally shoot a projectile in the direction he's facing, pausing momentarily as he does so.
