For Tex Avery, The Legend of Rockabye Point was a natural extension of a number of cartoons he made at MGM. One character tries to force another character to make noise and wake a third character who inflicts some kind of violence on the second character. Rock-a-bye Bear and Deputy Droopy are examples.
When Avery moved over to the Walter Lantz studio, he tried it again with The Legend of Rockabye Point. It’s a typical Avery cartoon in that it barrels along and as soon as one gag ends, the next one begins. In one, Chilly Willy tries to drop an anvil on the sleeping guard dog. These poses tell the gag.
Mike Maltese got a story credit in this cartoon but it’s really no different than the MGM “noise” cartoons written by Heck Allen. Don Patterson, Laverne Harding and Ray Abrams are the animators.
