Also like in BowserMovies1989's film Winnie the Pooh Goes to FernGully: The Last Rainforest (in which Crysta was revealed to be an old friend of The Good Fairy), Crysta will be revealed to be an old friend of Genie in this film. This film actually takes place after Pooh's Adventures of Free Willy 2: The Adventure Home, which explains Jesse, Elvis, Randolph, and Nadine already knowing Batty Koda. RatiganRules originally requested Yru17 to guest star Crysta alongside Batty Koda in that film, but Yru17 told him he couldn't because he wanted guest the characters from the first three Free Willy films in this film. Both Genie and Batty Koda were voiced by the late Robin Willaims. Both Aladdin and FernGully: The Last Rainforest were released in theaters in 1992. Kiara and Kovu were oringally planned to guest star in this film, but Yru17 decided to cut them out of the movie because RatiganRules is already planning to guest star Crysta and Batty Koda in Bloom's Adventures of The Lion King II: Simba's Pride. Aladdin, Princess Jasmine, Abu, Genie, Scrooge, and his nephews will face Hexxus again in Pooh's Adventures of Aladdin and the King of Thieves. Aladdin, Princess Jasmine, Abu, and Genie will see Crysta and Batty Koda again in Bloom's Adventures of Aladdin and the King of Thieves. This film actually takes place after Bloom and The Adventures of Ichabod and Mr. Toad (which explains Littlefoot and his friends already knowing Mr. Toad, Rat, Mole, Angus MacBadger, and Cyril Proudbottom). Crysta and Batty Koda will guest star in Littlefoot's later adventures after this movie.
The film will be dedicated in memory of Robin Williams who committed suicide on August 11, 2014.
