Seen it too many times...
At the time of me posting this, there are at least two Anti-Foamy movies. They're very short, and I see the humor in them, but I don't think they're very funny.
Try another idea. Do something else with Goamy. Don't just make him a squirrel hating rabbit-thing. Make him a series that's devoted to his adventures or something. This idea of hating other peoples' works is just old and I'm tired of it.
