SpongeBoss BulletPants is a mini-boss encountered in Psycho Krieg and the Fantastic Fustercluck DLC for Borderlands 3.


SpongeBoss BulletPants is a unique Goliath who can be found in a small hut near the third catapult in the Castle Crimson. He dual wields Bubble Blaster pistols.



  • When enraged, He will level up every time his HP drop below 50%. His name changes with every additional level. These names are the same regardless of game mode:
    • +1: SpongeBoss NoChance
    • +2: Super SpongeBoss NoChance
    • +3: Mega SpongeBoss NoChance
    • +4: Ultimate SpongeBoss NoChance
    • +5: Godly SpongeBoss NoChance
  • SpongeBoss BulletPants has an increased chance to drop the legendary P.A.T. Mk. III submachine gun.
  • While not enraged, SpongeBoss BulletPants dual wields Bubble Blasters.
  • At Mayhem Level 10, SpongeBoss BulletPants has approximately 1.3 billion HP. This makes him far more durable than even storyline bosses like The Graveward, which possesses around 800 million HP.


  • SpongeBoss BulletPants is a reference to Spongebob SquarePants, the titular character in the animated comedy television series of the same name.
    • The hut that SpongeBoss BulletPants spawns from is very similar to SpongeBob’s Pineapple, which is the residence of SpongeBob SquarePants.
    • It also references the term "bullet sponge" which is often applied to enemies in FPS that take an unreasonable amount of damage to kill. Fittingly, SpongeBoss BulletPants himself has a very large HP pool and fully heals each time he levels up.
