We are the Crystal Gems/Come on Grab Your Friends (Part 2)
Here is the Adventure Time portion of the art exhibit. I saw Kent Osborne in the gallery but, as usual, I got nervous and couldn't bring myself to say hello -_- Someone approached me and asked me if I went to Comic-con, because I looked familiar. I did attend the convention this year, but I couldn't remember where he was from. One of life's mysteries, I guess.
