so i'm rewatching spooky month (+ the new one) to get back in the mood of spooky month and i noticed that happy fella (the doll character with sadistic tendencies) has the same weird eye quirk as dexter the exterminator that got posessed by moloch (who also had sadistic tendencies)

my theory is that when moloch killed dexter by twisting his neck dexter accidentally possessed the doll and he's getting annoyed so his sadistic tendencies are getting heightened and that's why episode 4 happens
