Ever since Olaf (Josh Gad) sang his ode to the warmer season “In Summer” in the original Frozen, the Disney series has teased that the magical snowman could, and would, one day melt. While it’s never shown onscreen within Disney’s Frozen or Frozen 2, the short film Olaf’s Frozen Adventure answers the question fans of the lovable snowman have been worried about — what happens to Olaf when he melts? 

Within Frozen, Elsa (Idina Menzel) creates the snowman Olaf when she’s testing out the strength of her ice powers on the North Mountain. Based on the snowman Elsa and Anna (Kristen Bell) made together as children, Elsa unknowingly brings Olaf to life with her ice magic during the scene featuring her power ballad “Let It Go.” Olaf seems to be rather unaware of how heat affects snow, which is a running gag in both Frozen and Frozen 2. Within the short film Olaf’s Frozen Adventure, which premiered in theaters before showings of Disney’s Coco and as a Christmas special on ABC, it’s briefly revealed what happens to Olaf when he melts after he enters a sauna.

In the short Olaf’s Frozen Adventure, Olaf decides to visit each of the homes of the citizens of Arendelle to discover the best holiday traditions Elsa and Anna could adopt for themselves. Visiting the last house within Arendelle, Olaf asks Oaken (Chris Williams), the man from Frozen who owned Wandering Oaken’s Trading Post and Sauna, what kind of Christmas traditions he holds this time of year. Hoping it would be “the best tradition yet,” Olaf gets an interesting surprise when Oaken takes him into a communal sauna to enjoy the “Christmas sweats” with him and his family. As a gag, Olaf is revealed as a bucket of talking water. In retrospect, Oaken realizes that "the holiday sweats are for those not made of snow"and throws the bucket of Olaf out into the cold air. Olaf instantly freezes into solid ice, which Sven then breaks with his hoof, returning Olaf to his snowy self.

By Frozen 2, Olaf reveals that he is now permafrost — a term for ground that stays frozen year-round — as a result of Elsa’s strengthening powers. Not only is Olaf then able to enjoy warmer weather, as is shown within the opening of Frozen 2 as Olaf basks in the sun on a picnic blanket, but he no longer needs his own personal flurry cloud during the warmer months.  

Originally in Frozen 2, Olaf’s new situation was going to be thoroughly explained in Olaf’s own song “Unmeltable Me.” Olaf’s ballad, which is featured on the deluxe edition of the Frozen 2 soundtrack, details how Olaf no longer needs his own cloud flurry thanks to his new permafrost. Now that Elsa’s powers have increased, he has his own “self-refrigeration” and proceeds to brag about being “unmeltable” as he holds an enormous candle and cooly handles a sweltering setting. While the song was unfortunately cut from the theatrical version of Frozen 2, the same information was more subtly conveyed through a single line when Anna asks Olaf how he’s enjoying his new permafrost. 

Ever since Elsa ascended into the fifth spirit and became an immortal being within Frozen 2, it begs the question whether or not Olaf is immortal as well, since his existence is linked to Elsa’s powers. With Olaf’s new unmeltable permafrost, it seems unlikely that Olaf will ever melt again, making the scene within Olaf’s Frozen Adventure, which is now streaming on Disney+, the only time Olaf will most likely melt onscreen.
