Little Cat-Lamb Sylvan.
As Sylvan slowly journeys onward, she searches for both her mother and Granny Lili. She arrives at a wild strawberry land inside a glasshouse, where she meets a girl named Muir, who has experienced something similar to her. Perhaps Muir is another version of herself in this world. Muir has created her own world of paintings inside the glasshouse, but Sylvan seems to hear someone calling out to them. Together, they try to find a way out of the glasshouse.
The rainbow will always lift everyone up again and again.
