This is the first time that Luna Girl and Night Ninja are shown in one episode together, as well as the first time they work together (if Luna Girl being a referee can be considered teaming up with a villain).
Luna Girl nicknames Night Ninja as "Ninjy".
The four competitions between Catboy, Night Ninja, and later Luna Girl went as follows:
An egg-and-spoon race, which Night Ninja won due to Catboy dropping the egg by using Super Cat Speed.
A three-legged race, which Catboy, Gekko and Owlette won when Catboy's tail hit the finish line first.
A ball balancing competition which Luna Girl won.
A ball balancing competition while carrying an egg-and-spoon in their hands and a Ninjalino on their head which Catboy won after Night Ninja and Luna Girl interfered with each other.
This is the last episode of Season 1 that focuses on Catboy, as well as the last episode of Season 1 to feature Night Ninja as a primary villain.
