You heard word about a Great Bay Temple while you were visiting Termina and decided to set out and explore said temple. When you finally arrived, passing through the place, it felt rather serene, especially with the lack of potential danger. But you might've thought that too soon when you suddenly encounter an orange, life-sized, frog-like creature hopping around erratically, almost teasing you. Though it didn't seem malicious? Soon after it chanted something as sizable green drops ooze and drop from the ceiling, collecting themselves into a singular massive slimy blob. Those must be the Gekko and Mad Jelly you also heard about. Afterwards the Gekko hops into the Mad Jelly with a squish, slosh and glorp as they suspend comfortably inside. Maybe it'd be best to not make conflict with this intimidating duo. Though you also get the feeling they pose no threat as well.
