I was flipping through channels in the late 1990s and I came across an animated film or television show. It immediately caught my eye, because it featured a wizard who I immediately recognized as Radagast. Of course, I had never seen an animated Radagast, but this was a wizard robed in brown and animated in the style Rankin-Bass used for their versions of The Hobbit and The Return of the King. A line of nuts was levitating past him, as he inspected each one. (I think he found one that was unsatisfactory and kicked it out of line.)
Radagast went on dealing with the nuts for less than a minute. Then there was a bit of narration, and it switched to some elves or fairies, animated in the completely different style. I watched a little longer, but it did not seem very good, and I turned the television off after a few more minutes My hypothesis about what I had seen was that they had taken some Rankin-Bass animation that never made it into a movie and inserted it into another story. Does anybody know what I was watching?
