FAV! IMMIDIATE FAVORITE!! The background is so good, and then the white-ish lines outlining the Pines, and the colors, it's amazing.
Lol I can really see Stan and Mabel chasing Ford and Dipper, starting a water balloon fight, and Ford zigzagging around and yelling 'defensive maneuvers!' well Dipper turns around and starts chucking water balloons at Mabel and Stan, well Mabel has a water balloon in each hand and is bellowing a war cry as Stan just charges toward them (bellowing a war cry as well)
