Steven Universe - Rubo and the Cluster creature

It was about ruby and her twin sister came in the same birthstone. The birthstone cracked open and came the too twins out and had the same gems hands for each other. It was just long ago. Skinny ruby, emerald and howlite are going to secret world planet, it's very impossible to go that far away from there but they can do it and there are the cluster gems they can use there powers what ever they want choose to fight. Travel in a different planets lots adventures. It gave three gems names to change, rubo, yuna and baxle. And I believe they can save the world. I wouldn't forget rubo meets Matt it's a cluster creature.
