Gurdy Jr. is one of the bosses that can appear in The Cellar. She is one of the most common bosses to fight, particularly because she can appear in later chapters as a regular enemy.


  • Jr. can spawn a few Pooters.
  • She can shoot tears in eight directions.
  • She will charge the player at high speeds, bouncing off obstacles and walls, and thus losing speed.
    • Being as far away as possible from Jr. is advised.
    • The charge will destroy any Pooters between Jr. and the player.
    • If the player has enough knockback, or fires rapid enough, they can veer her off the intended course.

Champion VersionsEdit

Blue: Instead of one Gurdy Jr., there will be two smaller ones. This version has decreased health and only charges at the player, and drops a Soul Heart upon death.
Orange: Is slightly larger than the regular. She spawns Fat Flies and charges at the player, but does not shoot bullets of any sort.


  • Gurdy Jr. was added in the Wrath of The Lamb DLC for the original Binding of Isaac.
  • There are three other bosses in the Gurdy series, which includes: Gurglings, Gurdy, and Mama Gurdy.
  • Gurdy Jr. is female. [1]
