|A Tellun in the anime|
Tellun (テルルン), also known as Venus Heart Traps, Telulu Flowers, or Happy Blooms in the English dub, were plants designed by Tellu of the Witches 5. They appeared in the third season of the anime and the Infinity arc of the manga.
In the anime, Tellun were intended to remove Pure Heart Crystals from people. In the manga, however, they drained people's energy. Setsuna fell prey to a Tellun in Act 31, which made her re-awaken as Sailor Pluto.
