Not silly. Imagine the horror of being slowly warped into one, having your human features warp, and finally your head afalls off. And worst of all, you've been smooched by one of them. Gross, but not silly.
The skin kite, on the other hand, is very silly. I mean, it's a kite. Of all the awesome, gross, and creepy things you can do with human skin, some necromancer goes and makes a kite for his kids? Seriously?
