She was supposed to take the next job after Mimet's repeated failed attempts at getting Pure Hearts, but Mimet tried to trick her by using a voice changer to imitate Tomoe so she could take the job instead, but gave it away by saying "Ta ta". When Mimet entered Eudial's power device, Telulu pulled the plug on her, killing her instantly.
Telulu made one attempt to extract Pure Hearts, using plants called Venus Heart Traps to extract Pure Hearts from many people at once. Sailor Moon destroyed them all except one, which Telulu modified into a giant plant monster called Big Bertha. After Telulu lost all the Pure Hearts, Big Bertha turned on her. She electrocuted the plant monster, which selfdestructed, killing her.
Telulu attacks by extending vines from her fingertips and using them to electrocute her enemies.
