Gopher often says, "I'm not in the book." This has a double meaning: he's not in the phone book and he is also not in the A.A. Milne book. Gopher is the only Disney's Pooh character that did not originate in Milne's books. He was originally created to replace Piglet, until they decided to bring Piglet in for Winnie the Pooh and the Blustery Day (1968).
This was Winnie the Pooh's first ever animated short.
This featurette was originally released in the USA on a double bill with the full-length film The Ugly Dachshund (1966).
