Errors

 * In one scene Feedback had plugs on his hips, but in the next scene, they're gone.
 * While Ben 23 wears the Omnitrix on his left wrist (like the main timeline Ben), the billboard for the Secret of the Hero Watch movie featured the watch on his right wrist.
 * While Chicken Alien is facing the counter to order, there is an emblem on the diamond where his two sashes meet. While he is walking towards the door, the emblem disappears. It reappears while he and the Cow Alien are being sucked through the pinwheel aurora.

Allusions

 * A poster advertising the movie "Ben 23: Secret of the Hero Watch" is seen in the episode. This is a parody of the original series movie Ben 10: Secret of the Omnitrix.

Trivia

 * Cow and Chicken from Cow and Chicken make a cameo appearance in the Mr. Smoothy's 23rd store after Ben goes in and it hops dimensions. The characters' original voice actor, Charlie Adler reprises his roles for the appearance.
 * This episode was intended by the producers to take place sometime after Showdown episodes Part 1 and Part 2, because the Tenn-Speed and Feedback were received and unlocked, respectively, somewhere in the episodes before. These episodes however, have not yet aired.
 * According to Derrick J Wyatt, Ben painted the car Kevin gave him, and gave it to his mother. Hence, this is why he's using the Tenn-Speed motorcycle instead of his car.
 * While Feedback was chasing Liam there was a poster of Pax in the backround.
