i kinda forgot about this but here:
dance of the moonlight jellies (stardew valley ost)
slime sea sunlit waves and slime sea moonlit calm (slime rancher ost)
main theme, at sea, northern waters, shallow waters, oxbury, what will you leave behind, what will you leave behind reprise (spiritfarer ost)
submarine time machine (epic mountain/kurzgesagt ost)
and uhhhh. ig seagulls! stop it now (bad lip reading)
these are all just suggestions so if you don't feel like they fit you can even. not add any of them
