All Dogs Go to Heaven (Flash-animated film)

Plot
Taking place sometime after the events of the third film, after preparing to finish Elementary School, David decides to visit his Grandma Squeaker (Anne-Marie). Much to his surprise, he looks at an old photograph of Charlie, Itchy and his grandmother when she was eight years old. One day, he saw an old watch in the attic and as he slowly opens the watch, he hears a voice “Charlie. You can never come back.” A vision of Annabelle appears and he talks to David about the watch and Charlie. Soon after, he visits the library where he bumped into his 4th Grade Science Teacher to talk about time travel. He travels back to 1939 through the means of a miracle tape recorder from Annabelle and sees what it was like. Returning to the present, he decides that he should invite Charlie, Itchy, Sasha, Carface and Killer to New Orleans to see his Grandma Squeaker, who was surprised to see the former two because she had been a little girl during the last year of the Great Depression, when Charlie had died saving her from a fire and drowning, and she wouldn't have expected Itchy to survive either. Eventually, they encounter a robot-like wolf-dog named Cheyenne Baltoson, who came from 2199 AD to not have to see anymore of his future that had been devastated by a crustacean variety known as the "Ebi."
