Larry Jr.

Larry Jr. is a boss that can appear in the Basement and the Burning 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 Poop 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 Grub 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 [ | ]

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 Heart when defeated.

Green: Will occasionally shoot a projectile in the direction he's facing, pausing momentarily as he does so.

Trivia[ | ]

Larry Jr. appeared in the original The Binding of Isaac.
The Hollow is the posthumous version of him.
Larry Jr. is an allusion to Larries' Lament, the name for a group of bosses in Edmund McMillen's game, Super Meat Boy.[1]
- Not only do they look similar but smaller Larries came from a dead Larry in the Super Meat Boy credits. This is a strong indication that those smaller Larries and Larry Jr. are the same.
In battle, Larry Jr. seems to be crying and has blood on the lower belly of his body, unlike the splash screen before the fight.
Larry Jr. might be a reference to the centipede enemies from the 1980 arcade game Centipede.
