- This episode marks the second appearance of Rainbow Robin (her first being in the Season 1's episode, "Recipe For Disaster").
- This is also the first time Rainbow Robin causes legitimate oddness.
- Olivia Presti (Agent Oona) is listed in the episode's end credits, but is nowhere to be seen in the episode itself (or its B-plot). This is due to television airings of the episode(s) featuring a Gadget Guide interstitial in between episodes.
- The interstitial is not found in online releases.
