Season 4 Notes

  • Spencer Klein replaces Phillip Van Dyke as the (third) voice of Arnold
  • The theme song has been redone, although it's the same melody and the same opening animation (and Helga still says "Move it, football head!"); this is the second Nicktoon to do this (Rocko's Modern Life had its theme song redone after its first season)
  • Speaking of the opening, if you watch carefully, one scene has changed; when Helga says "Arnold" while standing behind the large "ARNOLD" on the ground, it's no longer drawn as if she's stretching it out
  • Storyboard and Animation Directors are now listed with titles in each episode's opening credits
  • Although "School Play" was shown at the beginning of the block of new episodes, it was made as a third season episode (and it has Phillip Van Dyke as Arnold), so it is listed in the third season episode list

Episode List

The fourth season of Hey Arnold! began on March 10, 1999, with new episodes running Monday & Wednesday nights.  ("School Play" was shown March 8, but it is considered a third season episode.)
