What the?

So I'm having breakfast in a cafeteria I go to the other day and I got to noticing the decorations.  And then these caught my eye:

Seriously.  What the hell are those things?  Christmas frogs?  The Martian elf contigent?  A bizarre chapter of the Nutcracker that I am not aware of? 

I admit that the last one is quite possible as I really know next to nothing of the Nutcracker Suite.

Should I be afraid?
