Humanities Help!!!?

Okay, for my gt Humanities cl (it is pretty much two periods back to back with the same teacher and it is basically civics, history, writing, English...) My teacher is having us all write screenplays and they will be submitted in a contest and then the drama department will perform the best one. I am doing mine on an islander (like Polynesian, Māori, and Tahitian) legend and I don't know any that would be able to be acted out so... any suggestions??????
