With how many of the new moves introduced in Sun and Moon turned out to be signature moves, which of them do you think other already established Pokemon should be able to learn? Although there are a lot, the one that immediately comes to mind for me is Strength Sap on Paras and Parasect. Parasect's got PokeDex entries discussing it draining nutrients from tree roots, and all things considered it would also fit well with the parallels between it and Shiinotic.
