Catty Cornered is a 1953 Merrie Melodies cartoon, directed by Friz Freleng, and starring Sylvester, Tweety, and Rocky. This is also the only speaking appearance of Rocky's gangster sidekick Nick, who may or may not have also appeared in "Golden Yeggs".
Summary[]
Rocky's gang, which only consists of Nick and himself, pulls off a bird-napping racket by kidnapping Tweety! Sylvester then decides to save the bird, but... will he save him from the gangsters or save him for lunch?
Rocky would bird-nap Tweety once again in The Sylvester and Tweety Mysteries episode "The Cat Who Knew Too Much", except that Rocky's sidekick is the idiotic Mugsy as opposed to the smart Nick.
