Ribert and Robert’s Wonderworld (partially found series)

Running for 78 episodes, Ribert and Robert’s Wonderworld aired on several PBS stations, usually on Sunday mornings. I remember watching it as a kid. Only three full episodes are on YouTube, along with short clips from the show: Colors, Rainforest and Ocean Life. Another bit of lost media was after the end of the credits, there was a recap of everything the viewer has learnt from the show. My memory is that it ended with Ribert on a black screen saying “See you very soon!” and goes down the screen. The show ended with the 1999 American Public Television logo as usual. The show ended in 2008, with reruns airing sporadically until around between 2012 and 2016. Watching PBS again on Sunday in around March-April 2016, it was nowhere on the schedule, it apparently stopped airing in general in September.

If anyone has more full episodes of this show, please let me know.
