Pooh, Simba, Timon, and Pumbaa's Adventures of Scooby-Doo is another upcoming Winnie the Pooh/Lion King/Scooby-Doo mixed crossover film planned to be made by Daniel Esposito. It is a prequel to Pooh, Simba, Timon, and Pumbaa's Adventures of Scooby-Doo 2: Monsters Unleashed. It will appear on Google Drive in the near future.
When Winnie the Pooh, Piglet, Tigger, Rabbit, Eeyore, Simba, Nala, Timon, and Pumbaa (along with Tennessee Tuxedo, Chumley, King Julien, Maurice, Mort, Terk, and Tantor) reunite with Scooby Doo and Shaggy, an army of monsters on Spooky Island have come to take over the island. Pooh, Piglet, Tigger, Rabbit, Eeyore, Simba, Nala, Timon, Pumbaa, Tennessee Tuxedo, Chumley, King Julien, Maurice, Mort, Terk, and Tantor are to help Scooby Doo and Shaggy and the Mystery Gang save the world from Scrappy Doo, who has taken over it.
- Tennessee Tuxedo, Chumley, King Julien, Maurice, Mort, Terk, and Tantor guest star in this film.
- This is an NTSC film with NTSC bits from the Winnie the Pooh films, The Lion King films, the Madagascar films, and the Tarzan films.
- Jonathan Oosterhof (aka LionKingRulezAgain1) originally made a separate Lion King crossover with the 2002 live-action Scooby-Doo film and uploaded it on YouTube in summer 2009, but it was later deleted, due to copyright claims and in late 2014, he retied from making anymore Lion King crossovers. Yakko Warner would then take over the remake version of that film and RatiganRules also originally planned to make a separate Winnie the Pooh crossover with the 2002 live-action Scooby-Doo film, but they decided to let Daniel Esposito make this film as a Winnie the Pooh/Lion King mixed crossover instead.
