Olaf makes a guest appearance in the Sofia the First episode "The Secret Library: Olaf and the Tale of Miss Nettle", where he is called forth by the Amulet of Avalor to assist Princess Sofia in her latest crisis; an evil fairy named Miss Nettle has been stealing the flowers of Freezenburg for unknown purposes. Unfortunately, the summoning of Olaf was a result of a glitch within the amulet, which was damaged by Nettle to prevent Sofia from using its power to foil her plans. As a result of this, instead of a princess, Olaf was brought forth, and though the snowman tries to return home, he finds himself unable to do so, again due to the amulet's damage. Trapped with Sofia, Olaf accompanies the young princess on her mission, during which he unknowingly provides useful advice by encouraging Sofia to push on with her quest to defeat Nettle, despite a lack of magic—using Anna as an example of a powerless human accomplishing the impossible by relying on perseverance.
After it's revealed that Nettle stole the flowers because they originally belonged to and were stolen from her, Olaf advises Sofia to use kindness and love to hopefully reform Nettle, as opposed to defeating her, as the entire situation was a massive misunderstanding. Sofia does so by informing the King of Freezenburg about the misunderstanding, who in turns commissions a festival honoring Nettle as the fairy responsible for providing the only flowers capable of growing in their eternally snowy kingdom. A touched Nettle reforms as a result, and fixes Sofia's amulet as a token of gratitude. With the power of the amulet restored, Olaf begins to magically return to Arendelle, bidding goodbye to Sofia and openly hoping for the amulet to break again, so that he may someday return to visit.
