I remember when I was a kid (early to mid 90s) there was a cartoon, in English, I think it was on Nickelodeon but I'm not positive, that was essentially a fairy tale/legend about the origin of the platypus. It was short, I'm not even sure if was long enough to be a full episode, but it was shown through the same show/special/event as the Rikki-Tikki-Tavi cartoon as well as other similar style cartoons. There was a storyteller aspect to the overarching show, I think. I don't know if it was current to the early 90s, or from earlier.
The story was that there was a chicken that was jealous of the ducks swimming in the pond, so she went to the fairy that ruled over the forest and asked her to be able to swim like the ducks, so the fairy gave her a duck bill and duck feet. But, she still had chicken feathers, so she'd go swimming and then have to sit forever in the sun to dry out. She saw an otter go by, so she went and asked the fairy for fur like the otter that wouldn't waterlog her. She lived like that for a while, but then realized she couldn't build nests like a chicken anymore, but saw a beaver building a dam, so she asked the fairy for a beaver tail so she could build a home in the water. After a little while, she went back to the fairy, who was getting irritated, saying, "What, are you still not happy??" and the platypus said she was lonely, so the fairy made her another platypus to live with her.
I've been searching for this cartoon for years, but I've never been able to find it. I can't even find anyone else who has heard of it. I was hoping someone on here might remember seeing this.
