Plot
Elsa plans to give Anna a surprise birthday party with the help of Brian, the Eeveelutions, Kristoff, Sven, and Olaf. But while Anna is led on a "party treasure hunt" by a string that winds through the kingdom, Elsa has caught a cold, and unknowingly produces a group of small animated snowmen ("Snowgies") with each sneeze, who begin to dismantle the birthday party's decorations while Kristoff tries to stop them. While Elsa takes Anna on the hunt, Kristoff, Sven, and Olaf try to control the Snowgies and fix the decorations in time for Anna and Elsa's return. After Elsa nearly falls off a clock tower, Anna convinces her to take rest. While Anna enjoys the party, Elsa sneezes a giant snowball through an alphorn, and stuns Hans overseas; whereupon Elsa rests in bed under Anna's care. Olaf, Kristoff, and Sven escort the Snowgies to Elsa's ice palace, where they stay with her snow-giant doorkeeper 'Marshmallow'.
