A Little Squirrel Music: Lionel hears an advertisement on the radio promising a lifetime supply of peanut butter to the winner of a "nutty" songwriting contest. He decides to create a song about Stanley and squirrels and heads to the garage to try to keep it a secret from Stanley. As he munches nuts for inspiration, he leaves the shells in the backyard, leading Stanley to believe that there's a mystery animal in the background. A trip into The Great Big Book of Everything ultimately provides valuable inspiration. A Boy's Best Friend is His Fish: When Stanley keeps visiting the fish shop, but won't tell Dennis anything other than that it's a big surprise, Dennis becomes convinced that the worst is happening. He thinks that Stanley is replacing him with a new best friend fish, one with more "pizazz." Remembering the good times that he had with Stanley, Dennis prepares a special gift, not realizing that Stanley has actually been planning a special gift for him all along.
