Games like jade cocoon

Jade Cocoon: Story of the Tamamayu (Japanese: 玉繭物語, Hepburn: Tamamayu Monogatari, lit. "The Story of the Jade Cocoon") is a role-playing video game developed by Genki exclusively for PlayStation. The game combines elements of role-playing video games and virtual pet management. It was developed by Genki in collaboration with Katsuya Kondō, character designer for the Studio Ghibli movies Kiki's Delivery Service and I Can Hear the Sea.

Jade Cocoon is set in a world where most of the land is covered in dense forest; populated by bizarre, mostly bug-like monsters called Minions. The only safe havens are small villages, one of which is the home of the protagonist, Levant. Levant is a young Cocoon Master, whose job is to capture and purify the Minions. The Minions can then be used to fight and defend Levant, spun into silk for money, or fused with other Minions to form more powerful combinations. As Levant captures more minions, his "Capture Level" increases, allowing him to capture monsters more easily.
