This is some kind of pan's labyrinth ending lol. As he's falling to his death he imagines his happy place, but makes the audience wonder of its a real ending or just in the birds head. Haha wtf this is a kids animation! Someone watched too much Guillermo del torro.
Who else is looking for that one show no one remembers the name of where they went InThe clock and there were the two siblings one a boy and one a girl
