  • Each of the Cool Kids resembles one of the Crystal Gems.
    • Sour Cream is tall, skinny, fair skinned, and his eyes, nose, color-scheme, and hairstyle resemble Pearl's.
    • Jenny's eyes and lips resemble Amethyst's.
    • Buck's color-scheme, sunglasses and lips resemble Garnet's. He also has a crease on his forehead (corresponding with Garnet's third eye).
  • 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.
