Biribiri is a Lemure sent by JunJun to help the Amazoness Quartet extract Dream Mirrors. He is an electric catfish with a microphone. He appeared in Episode 33 of Sailor Moon Super S.
JunJun sent Biribiri to put the audience of a ceremony to sleep, and PallaPalla had several nutcrackers extract their dream mirrors, which were then eaten by Biribiri. When the Sailor Senshi came to stop them, Biribiri tried to attack them, but short-circuited due to consuming too many mirrors. After a fight between the Sailor Senshi and the Amazoness Quartet, Sailor Chibi Moon called Pegasus with Twinkle Yell, and Sailor Moon destroyed Biribiri with Moon Gorgeous Meditation.
