- We're Heading Out (Rugrats in Paris)
- Take A Hint (VicTORIous)-Tracy and Tricia
- This is the first story to not feature the theme song this is most likely the author wanted it to be a quick case.
- When Tracy and Tricia sings "Take a Hint". The scene is played out is very similar to the scene in the VicTORIous episode "Tori and Jade's Play Date". The reason for this is that it's a parody of it. Fred and George-The annoying boys, Tracy-Tori, Tricia-Jade. Ironic thing is that both girls are portrayed by Victoria Justice and Elizabeth Gillies who also plays Tori Vega and Jade West in the show.
- The scene when Tracy and Tricia battle Dante is a parody of the battle in the Disney Channel Original Film Twitches where twin witches Camryn and Alex battle Thantos in an attempt of saving their friends and family from the Darkness.
- Fred and George Weasley, along with James Sirius Potter, Albus Severus Potter, Rose Weasley, Hugo Weasley and Lily Luna Potter makes their MCF debuts as minor characters. Fred and George Weasley won't make their official debut in Tracy Tennyson and the Goblet of Fire. While, James, Albus, Rose, Hugo and Lily won't appear again until Tracy Tennyson and the Deathly Hallows: Part 2. In the epilogue scene.
