Natron the First, the "Living Mummy". The mineral natron was one of the important ingredients in the mummification process in Ancient Egypt.
To get to Planet Roswell, you need to go through the Mogul system. A Project Mogul balloon was said to be the cause of the Real Life Roswell Incident.
Harsher in Hindsight: In "Eye of the Tempest," a mutated super villain wrecks a power station made up of two generating towers. The first one is damaged without much comment... But as the second comes down, Mira shouts, "Look out! The other tower!" amid falling rubble. Chilling in hindsight, as WTC North would do the same less than a year later.
The show does an episode (one of two actually) with Buzz and Booster crash landing on a world called Roswell where they're the aliens and the residents are the stereotypical green/gray alien the media usually depicts. (green skin, blacks eyes bald head, etc) Yet their town is effectively just like a normal human town. A few years after the show ends its run, a movie called Planet 51 is made detailing...you guessed it (though their aliens are different looking the premise is the same). What makes it funny? It's a CGI movie made by another company and this show was co-produced by Pixar, whose forte is CGI movies.
Wayne Knight voicing Zurg becomes especially hilarious when one remembers that the wrong Buzz Lightyear once speculated that Al, who was also voiced by Wayne Knight, was one of Zurg's minions when they inform him that he was the guy who kidnapped Woody in Toy Story 2.
In the DTV intro for "The Adventure Begins", Woody jokes that the toys just want to watch all the commercials on the VHS. With the advent of YouTube, it's become common for users to upload just the previews of various VHS tapes.
Ink-Suit Actor: Ty Parsec resembles his voice actor, Steve Hytner, down to the brown hair, face shape, and lines around his mouth.
Iron Woobie: Ty. He's been rescued by Buzz 50+ times, and yet he still keeps on trying to do his job and never thinks about quitting.
It Was His Sled: If you saw the show before watching the movie, you would know that Warp Darkmatter didn't actually die.
They Wasted a Perfectly Good Character: A lot of people think Ty Parsec had a lot of potential, whether as Buzz Lightyear's 'rival', or as the Tragic Villain Wirewolf - which would certainly be a variation on all the Card-Carrying Villain types in the show. But no, he's only in two episodes and they just say "The Curse of the Wirewolf is lifted". Even if everybody else turned by the ray gun was cured, since Ty was bitten by NOS-4-A2, he should still be a Wirewolf even if there was no way of him transforming into the beast - and destroying a whole moon by flying your hollow spaceship into it? COME ON PEOPLE.
Probably due to the show's nature as a spinoff, something like this was likely never going to happen (along with the fact that John Lasseter isnt fond of this show for some reason), but the show and its content is never referenced anywhere else in the Toy Story universe.
The episode "Super Nova" ends with Mira recovering from a fantastic addiction to energy. Her father lectures her that recovery isn't easy and that she'll likely be tempted to relapse every day for the rest of her life, except Mira's addiction isn't referenced elsewhere.
Ugly Cute: Villainess Gravitina is actually very sexy, but has a very large head.
YMMV tropes for the video game:
Catharsis Factor: Getting to kick Warp's ass at the end of Flamar 2 is a lot of fun, considering what a backstabbing scumbag he is revealed to be in the pilot movie.
No Problem with Licensed Games: While not a masterpiece by any stretch, it is still a pretty fun and simple game with a big variety of weapons, powerups and vehicles, a nice soundtrack, some challenging side missions, pretty cel-shaded graphics and entertaining gameplay.
