Recess (1997) is the only show from Disney's One Saturday Morning block that crossed over with Lilo & Stitch: The Series (the other three crossovers involved other Disney Channel original series), as well as the only such one to involve a series whose original production ended before Lilo & Stitch: The Series began.
This is the final time where the recess gang is on screen.
Ashley Johnson and Ricky D'Shon Collins are the only actors from the original Recess cast to reprise there roles.
