The Heavenly Slime is an enemy frequently summoned by the Queen Slime alongside Crystal Slimes and Bouncy Slimes. It flies around trying to ram into the player and is designed to divert attention from the boss, similar to the minions of the King Slime.
- The Heavenly Slime, Spiked Slime, Baby Slime, Slimeling, Crystal Slime, and Bouncy Slime are the only slimes without their own banner.
- The Heavenly Slime may be considered a Hallow counterpart to the Slimer, as it is practically the same. The only differences are that the stats have minor differences, and the Heavenly Slime does not have a wingless version.
- The Bestiary entry for the Heavenly Slime: "Crystal slimes on the purple spectrum grow wings much like their royal creator, becoming aerial threats."
