Well, while DC community boards is busy discussing about HIC fiasco and Doomsday Clock; Beast Boy got a mini story in this week's Dog Days of Summer special.

I think the story was nice, nothing ground breaking but pretty fun to read.
Bascially, Gar gets into the competition with some bully in the beach during his vacation, in which Gar managed to beat him in many competitons thanks to his shapeshifting power.
In the last contest in swimming, bully's friends tried to drown Gar with the fishnet, but Gar managed to freed himself by turning into the small fish that was just passing by and managed to win the contest.
Oh, he also made a friend in the beach, a deadpan nerd who was reading a comic book in the beach. They share a comic book at the end.
