Two Days Left
Medusa is first seen at the end of her lab, where she is working on a suitor for Sweetheart. Once finished, she expresses extreme satisfaction with her work, but Sweetheart is disgusted and attempts to storm off. Medusa interrupts Sweetheart and storms off herself.
After collecting the Slimy Key Card and using the Humphrey elevator, Omoris party finds Marina, Medusa, and Molly confronting Sweetheart, and Molly asks her for the 1 million clams she owes them. Sweetheart refuses, claiming that Omori and friends can pay for her before fleeing. Marina proposes they sell the children, but Medusa insists they simply ask for payment from them, to which Aubrey refuses. Upon hearing this, the Slime Girls become aggressive, eventually leading to a boss fight.
Upon being defeated, the Slime Girls briefly argue over how they're going to feed Humphrey without clams, and are then eaten by him.
Upon re-entering Humphrey, Medusas head can be found on the floor of her lab. She will ask Omori for snot to build herself a new body, which can be obtained by fighting Snot Bubbles. Upon completing this quest, she gives Omori a Mystery Potion.
