Mistletoe Edmund :)
Every year in Narnia, mistletoe would “magically” appear throughout the castle. No one would actually put it up during the official decorating of Cair Paravel so they were always confused as to how it got into the most random places. Edmund was, of course, the culprit. He found it a kind of Christmas version of his pranking. It was all fun and games until he got caught underneath it once.
