Simba, Timon, Pumbaa, and Pooh's Grand Adventure: The Search for Christopher Robin is another upcoming Lion King/Winnie the Pooh crossover film by LionKingRulez. It will appear on YouTube in the near future.
Simba and his friends have returned to the 100 Acre Wood once again as they help Winnie the Pooh and his friends find Christopher Robin in a place called Skull.
- Unlike the real film, which was released before Pooh's Heffalump Movie, this film is set after Simba, Timon, and Pumbaa's Adventures of Pooh's Heffalump Movie, due to King Julien, Maurice, Mort, Tantor, Terk, Louis, Genie, Sebastian, King Louie, Fu Dog, Rutt and Tuke, and Roger Rabbit being in this film.
- This is one of the only two Lion King crossovers that does not have the "Simba, Timon, and Pumbaa's Adventures of" title in the crossover title, due to the word "adventure" already being used in the real film's title; the other being LionKingRulez's other upcoming film Simba, Timon, and Pumbaa Meet Mary Poppins.
- Like Yru17's upcoming film SpongeBob and Pooh's Grand Adventure: The Search for Christopher Robin, this is a NTSC film with NTSC bits from The Lion King films, the Madagascar films, Tarzan, Tarzan & Jane, The Princess And The Frog, the Aladdin films, The Little Mermaid movies, The Jungle Book, TaleSpin: Plunder and Lightning, Brother Bear 1 and 2, and Who Framed Roger Rabbit.
