These things are too cute to ignore when they appear at night.

Someone had a lot of fun sticking them everywhere in towns and housing wards. The Mist ones have to be my favorite!
Is it possible we will see these as minions in the future? I want a spooky orange ghost friend! I'd even accept if their face was random each time they spawned since they have a cluster of different face textures for them.
