Some letters can’t be delivered in the usual way… but Sylvester has a if it's couriered by some energetic parachutists, a train speeding through the jungle, and a river packed with piranhas and pink dolphins, his letter is sure to reach its final destination. What makes this letter so important?   Well, Sylvester wrote it for his beloved G.G. (Greatest Grandma), whom he's missing, and it's filled with happy memories and loads of love. G.G. may be gone, but she’s still Sylvester’s favorite person—the most pickle-loving and fun person he knows!
