if your talking about for your mons to do things like surf if you go to one of mons and see it has a "skill" those are the hm moves so you don't need to teach hms to your mons just find one with the "skill" you need

Would you happen to know where the HM Deleter is? I've been looking ever since i got Pyra from the "rival" at the school, because I taught her Cut not initially realizing you don't have to teach it to them. I cannot for the life of me find out how to delete the HM and get to give her something more useful.
