The Twinkle Popper is a Hardmode, post-Lunatic Cultist ground enemy spawned by the Stardust Pillar during the Lunar Events. In addition to dealing contact damage, the Twinkle Popper can attack the player by vomiting up smaller enemies called Twinkles, which run around and can explode in to a fountain of damaging sparkles when close to the player or after enough time has passed.

- Desktop 1.4.2: Twinkle Popper's Twinkles no longer pick up money, as they would delete it forever during their explosion attack.
