Elsa plans to give Anna an unexpected birthday celebration with the assistance of Kristoff, Sven, and Olaf; yet while Anna is driven on a gathering treasure chase by a string that breezes through the realm, Elsa has contracted a bug, and unwittingly delivers a gathering of "Snowgies" with each sniffle, who start to disassemble the birthday celebration's adornments while Kristoff attempts to stop them. While Elsa takes Anna on the chase, Kristoff, Sven, and Olaf attempt to control the snowmen and fix the adornments in time for Anna and Elsa's arrival. In the interim, Elsa's condition quickly compounds and she gets ridiculous with fever. After Elsa almost tumbles off a clock tower, Anna persuades her to rest. They stroll back to the château where Elsa apologizes to Anna for "demolishing" another birthday, however Anna consoles her that she didn't destroy anything. As Anna goes to lead Elsa to bed, the ways to the palace open to uncover Kristoff, Olaf, Sven, and a pile of small snowmen, who shock Anna. Elsa sniffles again lastly observes increasingly modest snowmen that she delivered. Regardless of Anna's fights, Elsa finishes up the gathering by blowing into an alphorn. Notwithstanding, she sniffles into the horn, framing a monster snowball that unintentionally hits Hans abroad (and into a truck of compost, as he was clearing out the stables as discipline for his endeavor on Elsa's life). Elsa rests in bed under Anna's consideration while she calls attention to that dealing with her darling older sibling is the best birthday present ever. Olaf, Kristoff, and Sven escort the little snowmen to Elsa's ice royal residence, where they remain with her snow-mammoth doorkeeper Marshmallow.
