James Gunn decided to make Dragon Con the last stop on his Guardians of the Galaxy world tour and everything was coming up Groot.
Not only did he get a picture with Groot cosplayer HurleyFX, but he lead a bunch of people in the first official Groot off.
On a side note, if you haven’t seen what went into HurleyFX’s Groot cosplay, we previously posted pictures of it being created. It really is a masterpiece.
You can check out the Gunn led Grooting after the break.
