- Actor Allusion: In one episode Pleakley claims he and Jumba are "Canadians from Canadia." Kevin McDonald is Canadian.
- Cross Dressing Voice: Tress MacNeille, Tara Strong, Dionne Quan, Nancy Cartwright and Frank Welker for several experiments.
- The Kids in the Hall cast members Scott Thompson and Bruce McCulloch voice Pleakley's mother and sister Pixley, respectively.
- Executive Meddling:
- Producers hated Angel and didn't want her to appear again. After finding out about her popularity among fans, they relented.
- On the other hand, Keoni Jameson was mandated by Disney execs as an audience avatar, and the writers hated him for it.
- The show was originally conceived as an action-adventure series with a similarly sombre tone as the film, but Disney Channel wanted something Lighter and Softer.
- Fan Nickname: 627 is given the name "Evile" by fans and wikis due to "evil" being the only word he said, at least initially. That being said, he was never named by anyone in the franchise proper.
- Missing Episode: The crossover episode with Recess never aired on Disney Channel, possibly because the network was worried that the kids that were into Lilo & Stitch would have no idea what Recess is.
- No Export for You/Keep Circulating the Tapes: The Series has been fully released on DVD, but only in Japan and Greece. "Mr. Stenchy" and "Clip" were released on a DVD game called Lilo & Stitch's Island of Adventures, and "Link" was a bonus feature on the Leroy & Stitch DVD. Also, all four Lilo & Stitch films are on Netflix, including Stitch! The Movie and Leroy & Stitch, but not The Series, leaving a huge gap and a lot of missing context if one were to watch both those films without having seen The Series.
- Talking to Himself: Lots of them, including Jeff Bennett, Nancy Cartwright, Grey DeLisle, Tress MacNeille, Rob Paulsen, Chris Sanders, Tara Strong and Frank Welker.
- Technology Marches On: In "Houdini", Lilo tells Mertle to set her VCR (likely for recording the planned special for Stitch's magic act), a device which was already in decline at the time and would become completely obsolete in just a few years.note
- The Other Darrin:
- In one episode, Kevin Michael Richardson voiced Cobra Bubbles. Ving Rhames does voice the character though, but it's unknown which episodes.
- Dee Bradley Baker replaced Jason Scott Lee as the voice of David in the TV series.
- In her first appearance, Victoria is voiced by Daveigh Chase, which lead to Talking to Herself with Lilo, and in her second appearance, Alyson Stoner voiced her.
- What Could Have Been: Precious (Experiment 400) was meant to have her own episode as a parody of The Lord of the Rings where she would be thrown into an active volcano where the extreme heat from the lava would defeat her but alas, the idea was scrapped due to copyrights. Now why they couldn't use Yang for a lava source is beyond anybody's guess.
