Pls help me find this stop motion short about blue pearls

I’m looking for a stop motion animated movie, short film probably, max 30 min-ish, but much more likely something between 10 and 20 minutes…It’s about a girl and her grandma I think and the whole story is that there is a great drought in their land. The girl has a necklace which contains blue pearls and one of the pearls is almost being swallowed by the girls baby sister. But then she spits it out, and the pearl lands in the sand. And it finally brings rain. I remember not liking this little animation as a child, but it would be so cool to find it, so I can rewatch it maybe. I’ve seen it after 2009 and before 2014 for sure, in the Hungarian television program, probably at channel m2. I believe the word “pearl”, in Hungarian “gyöngy” was in the title, but I don’t think it’s a Hungarian short. If you have any idea or any memory of this, I’d appreciate any kind of help!
