"Cartoon All-Stars To The Rescue" was an animated special that was aired on ABC, CBS, and NBC in April 1990, featuring a crossover of various cartoon characters such as those from ALF, Alvin And The Chipmunks, Disney's DuckTales, Winnie The Pooh, Muppet Babies, Teenage Mutant Ninja Turtles, Garfield And Friends, The Real Ghostbusters, The Smurfs, and Looney Tunes. Since ALF, like all the characters from the shows listed, was presented as nothing more than a cartoon character come to life, and since this adventure doesn't tie in with any known stories he has in his animated series, it is considered "non-canonical".
