KeroKero Musume was a Lemures used by VesVes when targeting Toshiyuki Nishino for his Dream Mirror. She appeared first as a tadpole, causing Sailor Moon and Sailor Chibi Moon to exclaim over how cute she was, but they quickly changed their minds when she "powered up" and metamorphosed into her full frog-like form. VesVes trapped the Sailor Senshi inside of a computer to prevent them from interfering as the Lemures swallowed Toshiyuki's Dream Mirror.
- The "Kero" (ケロ) part of her name means "frog."
