Those Changeling remind of of Koosalagoopagoop. Yeah, I pulled waaaaayyyy back there for that one.
It was too simplistic an ending for such a complicated build up. It's like watching this beautiful pre-sneeze face build up for some sort of wonderful sneeze, just to watch the person have a horrible sneeze you hate, or not sneeze at all.In this case, the episode sneezed, and we got those super ugly new Changeling characters, they represent the nasty boogers.
