This episode references the negative reception of Sparky and Chloe to a lesser extent, and that they were forced upon by the executives. Timmy mentions that Sparky had to be kicked off the show due to him being very difficult to work with, referencing how he was absent in season 10.
This episode also references the overusage of Crocker and Timmy's dad from season 7 onwards.
Trixie notes that her briefappearances in "Birthday Battle" and "Dimmsdale's Got Talent?" were actually done by her silent stunt double. Chester McBadbat and A.J. then note that their appearance in "Dimmsdale Tales" were also done by stunt doubles, but they note that they "at least had a few lines". Trixie is confused as to why the network was able to afford speaking replacements for Chester and A.J., but not her, as a reference to Chester and A.J. having their voice actors replaced in season 9, but not Trixie, who didn't have a speaking appearance since season 7.
