Season 3 Notes

  • The character Lorenzo was (I assume) supposed to appear first in "Rich Kid", but he's in the class when they sing in "Gerald's Tonsils" and he plays a large role in "Arnold's Room", both of which aired before "Rich Kid"
  • One of the scheduled episodes ("Part Time Friends"/"Biosquare") was originally made for the first season (it's the only episode with Toran Caudell as Arnold not shown in North America yet)
  • In the credits, under "Animatics", is "Brian J. Arnold"
  • "Part Time Friends/Biosquare" was originally made with the first season episodes but, for whatever reason, not shown until now; these have the "original" actors (including Toran Caudell as Arnold), include the Games Animation logo, and are animated by Wang Film Productions instead of Sae Rom
