From The Lost Media Wiki
The episode guide throughout appears to have a mix of episodes from the 1970-1971, 1974-1977 and 1989 runs of the show. I'd say use French Wikipedia for the 1989 episode guide, and see if you can identify which might be "Ermintrude Gets Stuck" (the only 1989 episode found in English).
