This is Icarus. He wanted to complete a challenge by summoning..... something. He doesn't know what or where it is (can you spot it?). His friends can be cruel and challenge him to unusual things, this is just one of many.
When I first saw the background I knew I had to use it for something. I would've given Icarus wings as a costume but I don't have any and have no clue how to get any unless I pay for it (which I'd rather not do).
(The thing he summons is the fish bones and rat )
