The Mouse Queen

This is obvious as her mother is a queen and her father is a knight.

Life passes in idyllic splendor with her stuffed animal companions Captain Bear and Sergeant Mouse.

Then the trolls arrive in her wardrobe with a desperate message from the town of Straw-on-Water.

The Mouse Queen is a prisoner of the diabolical Beast.

It is up to Scarlet, Captain Bear, and Sergeant Mouse to rescue the Mouse Queen across a wondrous realm where Scarlet learns that things aren't always as they first seem.
