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 sees 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 she talks to David about the watch and Charlie. Soon after, he visits the library where he bumped into his 4th Grade Science Teacher, Abner Collier, to talk about time travel. Mr. Collier remembers that his cousin, Richard, died of natural causes in 1980, after traveling to 1912. After getting the proper research from him, David, with the help of Annabelle, decides to dress up in 1939 attire, then back to 1939 through the means of a miracle tape recorder and sees what it was like. Annabelle reminds David that the people are part of a flashback and they cannot see or hear them.

Returning to the present, he decides that he should invite Charlie, Itchy, Sasha, Carface and Killer to New Orleans to see his grandmother. Upon arrival, Charlie and Itchy howl a snippet of Love Survives. Anne-Marie recognizes the song and was surprised to see the them 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. Annabelle then takes them to the events of the second film, which Charlie and Sasha first met and got married. As they return to the present, the dogs notice a strange beacon that, even much to Annabelle's stupefaction, simply appeared in the atmosphere… the dogs 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." They also meet two kids that Cheyenne are looking after named Philly and Tilly, who are the first friends he made when he traveled to their time.
