So I have an idea for the Dolphin if you dont have anything planned for it yet.
Long story short I lost myself watching many videos of someone which make Ytb short about weird animal like a fish who doesnt know how to swim and fun facts about animals like the fact that Sea Lion are actually dangerous psycopath torturing their pray for hours (scarry, very scarry, I wish I never reincarnate as a penguin.)
Any Way, After a moment I fall on that video which explain how horrible Dolphin are (because yeah idk if you knew, for myself i already knew before that short but yeah Dolphin are not as kind as you may think...) Just pay attention to the first 3 seconds and even the last 2 seconds also if you want but the 3 first are enough to understand. (The video is in french btw sorry)
So I thaught it actually could be great as inspiration for the Dolphin in Insect Prison, Like the option which allow to gaze at sea could be move to a sort of small wood dock or something that allow dolphin to come closer to you since they obviously need a bit of deep water to swim and well some thing could happen like Leah Gazing at sea and suddenly a dolphin appear wondering what shes doing and Leah could be like "Oh hello Mr. Dolphin what are you doin?" and depending of your lust level like above 60% the dolphin could feel it and be enticed by it and start mating and as usual the scene could be slightly different depending of your Lewd level.
