Actor Allusion: In "Sham Pooh," a mix up leads to all the characters acting like each other. Owl winds up thinking he's Pooh and acting like the real deal, which isn't too much of a stretch for his voice actor as Hal Smith was Pooh's voice actor as well in the early 1980's. Smith does do a pretty good job of differentiating his voice for Owl-as-Pooh compared to the regular one he used for Pooh.
Hey, It's That Voice!: A mix of old and new Pooh regulars- Piglet, Owl and Tigger (most of the time) had their original voice actors. The current Pooh and usual modern voices for Eeyore, Rabbit and Gopher started voicing their characters around this time. The voices for Kanga, Roo and Christopher Robin were pretty much just for this series.
Keep Circulating the Tapes: A few episodes are available on the Growing Up With Winnie The Pooh DVDs and many VHS tapes contained episodes of the series back when that format was commonplace, but the vast majority of the series remains difficult to find. For those that have thrift stores, Goodwills or swap meets in their area, the VHS tapes are not uncommon finds there, along with a VCR to play them if you don't have one, often selling for $5 or less.
The Other Darrin: Halfway through the show's run, Jim Cummings, already voicing Pooh, replaced Paul Winchell as Tigger as well. (Winchell was very much still alive at that point and returned to voice Tigger in Pooh's Grand Adventure.)
