KEL TU 007 is a comic published on tumblr in 2013 by Kelly Green.
The comic parodies a piece of official art which also depicted the Hitchhiking Ghosts piled up on top of one another.
”This is kind of obscure, but it’s supposed to be in reference to Ron Cohee’s design for the Hitchhiking Ghosts – the one we’ve been seeing everywhere. I actually really like his design; it’s cute and energetic. But I can’t help but wonder, in the appropriate context, why it is that they’re stacked on top of each other like that. A new tactic to grab attention, perhaps?”
