  • During April 1st (April Fool's Day), the Sponge's sprite changes to a cube resembling a real life cleaning sponge.
  • The Sponge gets its name from the term "damage sponge" due to its ability to increase the defense and survivability of the player.
  • In previous versions of the mod, the Ambrosial Ampoule was used to craft this, thus inheriting its effects.
