Marshmallow is a Frozen minifigure introduced in 2017.
Marshmallow is a huge snow monster who served as Elsa's bodyguard. Elsa first creates him to kick out Anna, Kristoff and Olaf when they come to convince her to return to Arendelle which she refuses. He pursues the trio off the North Mountain and later attempts to protect Elsa's castle when Anna's fiancée Hans arrives with an army to capture Elsa, only to fall presumably to his death when Hans cuts off one of Marshmallow's legs. Later, Marshmallow returns to Elsa's castle and reclaims her tiara, making himself king of the North Mountain.
