It's all fine and good that COPPA is doing it's job with protecting Children under the age of 13. But at the same time, It only furthers the American stigma that "CaRtOoN's ArE JuSt FoR KiDs!"
Until the day mainstream America stops shaming it's own animation industry, Newgrounds will be around as the only sanctuary of True animation.
But as for this animation short: It is well made! trying to show the audience that cartoons are not for kids. Despite the main character/animator being a little childish himself. Very entertaining.
