Mermaid Comb of Merroway Cove

Oona's Comb is a magical hair comb with the power to control waves.

Background
The comb was originally given to Oona by her mother, much to Cora's disappointment. She was told it possessed magical powers but would not tell her until she was old enough.

It was that Queen Emmaline and Cora only knew about the comb's magic but it turns out so does Cedric. He came along with the Royal family aboard the Floating Palace in search of it and then use it to take over the kingdom of Enchancia.
