Frostine is a small female kitten who wears a blue tiara with silver oval-shaped jewels inside it. She wears a blue bow on her fluffy tail with a blue bead necklace with a silver heart-shaped jewel hanging from it. She also has pure-white fur and blue eyes that are the same shade as the rest of her jewelry. She is Elsa's cat.
Frostine was a birthday present to Elsa from Anna. It was Snowing and Anna saw the Kitten shivering in the cold and took her inside to warm up and thought of an idea maybe she should give her to Elsa!
