- Crossdressing Voices: Janice Karman voices some of the young male characters, such as Kevin, Neville, Basil, and others. She also continues voicing Theodore.
- The Other Darrin: Ross Bagdasarian Jr. and Janice Karman's daughter Vanessa took over the role of Eleanor from her mother while Karman still keeps the roles of Brittany and Jeanette.
- Recycled Script:
- "Principal Interest" is very similar to "Romancing Miss Stone," an episode from the 1983-series—one of the main differences between the two episodes is that Dave ultimately doesn't end up with the principal, for two reasons: 1.) Dave and the principal aren't romantically interested in each other, and 2.) The principal turns out to already be married.
- "Wax Dave" is also similar to the 1983 series episode "Whatever Happened to Dave Seville?".
- Role Reprisal:
- Ross Bagdasarian Jr. and Janice Karman reprise their respective roles as Alvin, Simon, and Dave, and Theodore, Brittany, and Jeanette.
- In the Latin American Spanish dub, all the characters reprise their respective roles from the live-action films.
- Talking to Himself: As mentioned with Ross and Janice voicing several characters, their kids Vanessa and Michael also voice numerous background characters.
