- The Land Before Time VI: The Secret of Saurus Rock, The Lion King II: Simba's Pride, Scooby Doo on Zombie Island, An American Tail III: The Treasure of Manhattan Island, Mulan, and Barney's Great Adventure were released in 1998.
- Most of the Jungle Adventure Crew are in this film because Simba, Timon, and Pumbaa are already in the Ronald McDonald version.
- Yru17 originally planned to re-edit this film, but he retired from re-editing anymore crossovers, so Shadow101815 will make this film instead.
