Last one to the final house is a pair of wax limbs!
An obvious reference (if you hear it correctly) to the third episode, Headhunters.
Robbie posters on the back of Wendy and Robbie's van
I can't say I'm surprised that Robbie would put posters for his band on the back of his own van. An interesting observation though.
If only there was something we could use to cover our bodies and faces with. You know, like a disguise of some kind.
While Soos could just be thinking out loud and not really have realized what he said, I think it's more likely that he knew exactly what he was saying and wanted to keep his naive appearance intact. We know (because Bill said it twice) that Soos is smarter than he seems to be.
Soos playing with the cackling head
Again, Soos could just have been extremely stupid, but I think he was trying to expose the monster so that a) he could show Gorney the way out, and b) he could get eaten, eat his way out of and destroy the monster, and save the kids. He simply used the cackling skulls as a convenient way to win the battle without looking like a genius. The only question is: why is Soos attempting to look dumber than he really is?
Dipper's shield - Bill
Dipper's shield, which he apparently got in the Summerween superstore, has a picture of Bill Cipher on it. Again, this is 7 episodes before his official introduction, but there's something more here. Why would the store sell that shield to begin with?
...with, like, that white powder stuff on it... / How did he get 2 free hands? He only had one before.
I ate a man alive tonight.
