I hope I'm not the only one who obsessed over this web series. (if you haven't, go watch it. It's actually quite good)
Anyways, like anything I obsess with, I have to type the characters.
Nikki: Almost textbook ESFP
David: ESFJ but could see arguments for ENFP
Space Kid: ENTP!
Dolph: INFJ? I mean come on, he's literally Hitler!
Daniel: He's literally Jim Jones so ENFJ
The valley girls: ESFJ
