A small rock.


  • The rock gets wedged in Isaac's head and makes him bleed.
  • Increases Damage by 1, increases Tears by 0.2, decreases Speed by 0.2, and turns tears gray.


  • This is most likely to be a reference to the biblical story of David and Goliath, where David kills the giant known as Goliath with a small rock, hence the name.
