Hey, I would normally be mean, but...
You guys are only 10, so I won't hold it against you that you can't make a good flash cartoon. Hope you guys learn to animate better stuff in the future, you're only 10 though so you have years to improve your skills. When I was 10 I couldn't even make a flip book, not because I didn't know how, but because I was lazy. You guys need to work on your jokes though, a fish eating mario isn't that funny of an outtake, maybe if Mario accidentally fell on Princess Toadstool and ripped off part of her dress exposing her, or something like that. Well, good luck in the future and keep trying. Hope to see some good stuff from you guys in a few years.
