Marshmallow is the enchanted snow-monster that queen Elsa created in Disney’s Frozen. He was created to serve as her palace guard but eventually inherited her palace as his domain when she returned to Arendelle. Marshmallow looks like an enormous icy snowman and acted like a brute bodyguard when Anna and Kristoff intruded the palace. He’s very protective and devoted toward Elsa, which led him to be aggressive.
