- Kid Rhino were sent a separate master tape copy of Surprise Adventures to use for the season 5 songs, this was discovered due to the songs having proper recording levels as opposed to the Surprise Adventures CD which has the audio set slightly too loud causing clipping.
- The beginning of the songs, It's Great to be an Engine, Harold the Helicopter and Donald's Duck are cut out, as they were taken from the master tape of the 1998 audio story, Surprise Adventures, where Michael Angelis spoke over those parts.
- "Thomas Theme (Reprise)" is a duplicate of the opening theme instead of the actual closing theme.
