There are basically four new scenes in this build, vaginal with Kuvira on the beach, butt stuff with Toph at night, Two new/old girls can be found and they'll give you a hand. I'm also finally giving you the often alluded to Beifong Boobs on the beach scene. There's a job to be done and it involves boobs! The grotto can be explored. It's a small grotto.

A few more spoilers for if you want. You can help Ikki find real treasure, an old snake statue, cum on Pema and meet two other new/old characters who will arrive "on the island". All you can do right now is look at their idles though. Oh, I added a small new thingy to the pema/Oogi scene and probably did some other things here and there too which I can't remember. ps. the stuff you can find in the treasure doesn't have any consequences right now in this build.
