This is the only episode to have various guest stars: James Arnold Taylor (Sprig), Richard Horvitz (Chuck), Nika Futterman (Ani), Justin Berfield (Ving), Michael Clarke Duncan (Rockwell), Moe Collins (Ma Speevak), Pat Fraley (Brock Rocket) and Queen Latifah (Pam Dromeda).
As stated in the main body of the article, this episode was intended to be the pilot for the spin off series titled Crash Nebula, but the series was never produced (for unknown reasons).
This is the second time an episode features a different type of animation than the normal type; the first time is in Channel Chasers.
This episode features two ending title cards, one is the same as the beginning title card and the other one features a TV where the screen was seen in space.
This is the first normal episode to not start with a title card. The second and final is Timmy the Barbarian.
This is the second episode where Timmy does not make a wish. The first was in The Big Scoop!. This is because he only appeared in two scenes.
This episode focuses on Crash Nebula instead of Timmy Turner who only appears at the beginning and end of this episode.
This is also Timmy's shortest role in the entire series.
Innuendo: Ani touches her breast to get a helmet to breathe in space.
The fuel for the Nebula outfit is cow poop.
In Latin America, this is the last episode to premiere on Jetix (previously Fox Kids, today Disney XD) due to the new episodes that are premiering on Nickelodeon for that location.
This is the last episode Bob Boyle is credited as the Art Director.
Crash Nebula - The title is named after the "Crab Nebula", an explosion that happened in 1054.
Danny Phantom - An easter egg is shown when Sprig is looking at his comic. If you look closely you will see that Danny Phantom is shown on the back of the comic, it says "Butch Hartman's Danny Phantom", and a caption that says "Coming Soon". This means that in Sprig' universe is some date before April 3, 2004.
Also, in the Danny Phantom episode "What You Want", when Danny and Tucker were at the movie theater, they were playing in a "Crash Nebula" arcade game.
