SpongeBob and Pooh's Grand Adventure: The Search for Christopher Robin is the first full-length SpongeBob SquarePants/Winnie the Pooh crossover film planned to be re-edited by yru17. It is unknown when the film will be shown on YouTube.
SpongeBob SquarePants, Patrick Star, Squidward Tentacles, and Sandy Cheeks return to the Hundred Acre Wood to reunite Winnie the Pooh, Piglet, Tigger, Rabbit, and Eeyore as they help them find Christopher Robin and bring him back from Skull.
- This is the only full-length SpongeBob SquarePants/Winnie the Pooh film that does not feature any guest stars (as Yru17 wanted to re-edit a single SpongeBob crossover with a Disney film without any guest stars at all and thought that the real film was set before Pooh's Adventures of The Land Before Time), as a few more full-length SpongeBob SquarePants/Winnie the Pooh films from SpongeBob's Adventures of The Tigger Movie onwards will guest star Littlefoot, Cera, Ducky, Petrie, and Spike.
- This is an NTSC film (taken from a Disney Channel airing of the film) with NTSC bits from The SpongeBob SquarePants Movie.
- The short film Pooh's Adventures of SpongeBob SquarePants: Fools in April was originally planned to be shown as a double feature with this film, but Yru17 decided to move the short film to being part of a double feature with Pooh's Adventures of Stand by Me just to avoid copyright claims when he uploads the film.
