I get all the references except the middle one.
For those who want help on the rest:
Boos from Mario __ PacMan Ghost __ Casper
Pokemon __ ??? __ GhostBuster’s Slimer
Patrick Swayze’s Ghost __ The Ring __ Supernatural
After talking with several co-workers, we came to the conclusion that it represents Beetlejuice when he had the carousel head.
The TV could also be from the movie Poltergeist. “They’re Here”
I didn’t get that one either, but Beetlejuice would make sense since you have to intentionally call him.
I thought Poltergeist first.
