A film that was on cartoon network about 4 animals (dog, cat, donkey and something else) who were in a band and they were took on by a food company to sing their theme song and then it turns out they are evil.

That's all I can remember

Oh, yeah, that I couldn't forget this one if I tried :). It's the dog, the cat, the donkey, and the rooster of "Fearless Four" or the four Bremen Town Musicians, most notably reviewed by the "Media Hunter" there - His Review huh ;), and even though that I haven't seen this VHS tape version as of yet, that I think that I still prefer the "Happily Ever After: Fairy Tales For Every Child" HBO kids show episode remake version of it myself, huh friend :]? >Danny<
