- Each of the Cool Kids resembles one of the Crystal Gems.
- The Cool Kids' personalities match certain aspects of each of the Crystal Gems'.
- Jenny is fun, carefree, tomboyish and counter-dependent, like Amethyst.
- Buck is stoic, quiet, level-headed and independent, with more going on inside his head than he shows on the outside, much like Garnet.
- Sour Cream is artistic and cares about rules such as seat belt safety, similar to Pearl who cares about road safety to the point of not playing a racing game correctly. At the same time, he's also a rebel against what he's "supposed" to be (a fisherman) and both are partly uptight.
- Sour Cream has the most appearances of all the Cool Kids.
- Jenny is the only Cool Kid to not have a solo focus episode.
