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.
