Hold on, let me port my long geeky explanation of this over-

In case it's unclear: Rigby/Ghost Kid and Sock are both supernatural creatures who should be able to high five, right? The former is semi-tangible (basically solid-feeling, because of his high power level), and the latter is an intangible, incorporeal ghost-demon-thing. Because of that, Sock phases right though Rigby/GK's hand as if he were a tangible human. 😐

I'm not sure why I drew Rig looking annoyed, but it kills me every time I look at him 🤣

(Is Sock cold? Can he detected? Like... would he pick up like a ghost? Yeah wait, can Rigby just see him?? Is he a medium now??? (Oh right duh) But, his does his ghost sense go off around him?? He could probably see him while no one else could????? Then he and Jonathan could be the local crazies together. 😋)

Edit: I like this picture. I'll probably clean it up and finish it maybe. 👀
