Franklin is over at his Granny's house for a visit. Granny says she has a surprise for him and Franklin thinks it's chocolate-chip cookies. Actually, it's Possum. She babysits him sometimes and today she invited him over to her house. Franklin recognizes Possum. She has pictures of him on her mantel. Granny explains that she used to babysit Possum's Mom. She wants Franklin to get to know Possum and has them come outside for a picnic. Franklin is looking to his favorite sandwich, but when he bites into his sandwich, it's not peanut butter and lettuce, it's watercress. That's Possum's favorite kind of sandwich. They go into town and everybody recognizes Possum. Granny's told them so much about him and how he sends her letters. Franklin asks if he can send Granny a letter. Then, later, Franklin wants to play checkers with Granny. But you can't play checkers with three people. So they play cribbage, which Possum is especially good at, instead. From there, the two start competing for Granny's attention, helping her out with stuff and picking all of the flowers in her garden when she asks for some flowers. Finally, the two actually talk with each other. Possum thinks that it must be neat for Franklin who have a Granny who lives so close to him. His Granny lives so far away, he has to take an airplane to see her. Also, whenever Granny comes to babysit him, she brags about Franklin all the time. Franklin's surprised to learn that Granny brags about him. He decides that he can share Possum with Granny and they can both be her favorite "grandturtle."
