Clumsy witches

You've been appointed as instructor for a group of witches. The problem children. They have to be doing this on purpose, right? "I-Instructor! Help! I can't untie these!" "Wah, Instructor saw me eat the dirt!" "T-teacher? You know a drying spell, right?" Cannot understand what she's saying, but likely saying "Please get me out, Instructor!" "I fell off my broom. I hurt my belly, see? Can you see it, teach?" The last one is 100% doing it on purpose!!!
