Years have passed since Frosty left for the North Pole, but kept his promise to the children that he would be back again someday. When he hears the news about the first snowfall of the season, he comes back to the children. The children are excited to hear about Frosty's return and are overjoyed when he comes back to play with them, but then Jack Frost sees the fun that the children are having with Frosty and becomes jealous of him. When he learns the origin of Frosty and his magic silk hat which brought the snowman to life when placed on his head, Jack decides to steal it from Frosty so the children will love him more. But that night, while Frosty and the children were ice-skating at the frozen pond, Jack unknowingly and mistakenly captures the male horse's old hat with his ability to blow snowy winds. Believing it to be Frosty's hat, he disappears with it. Despite the fun he has, Frosty becomes sad and lonely at the end of each day when the children go home for the night, making him cry for the first time. To cheer him up, the kids, with his help, build a snow wife the next day and name her Crystal, but she is not alive like how he is. The children try placing the female horse's bonnet on her head but to no avail. Meanwhile, Jack soon looks upon the stolen hat from the male horse and discovers he was tricked. Realizing that Frosty was the cause of his failure, he swears revenge on him. Late that night, Frosty presents Crystal with a bouquet of frost flowers. His gift of love brings her to life, and she says his trademark line: "Happy Birthday". The two joyously frolic through the snow, until Jack uses a gust of icy wind which blows Frosty's hat off, turning him back to his lifeless state and taunting Crystal that he is gone for good. To prove Jack wrong, she sculpts a corsage out of snow, places it on Frosty's chest and gives him a kiss which immediately brings him back to life. Befuddled by his reanimation, Jack throws Frosty's hat back on his head. Frosty and Crystal run through the town announcing their wedding to the children. The children gather together with Parson Brown, the local preacher, in town to marry them. Parson Brown says that the marriage would not be legal as he can only marry real people. Everyone is despondent until Parson Brown suggests they build a "snow parson" with his assistance. After the parson is built, Parson Brown states that "A parson is not a parson 'til he holds the Good Book in his hand." He places his Bible into the snow parson's hand, and like Frosty and Crystal, he is magically brought to life. Jack witnesses this and decides to spoil the wedding with a blizzard. Frosty and Crystal decide to reason with him and ask for him to be the best man at the wedding. Finally feeling appreciated, Jack agrees. The wedding goes on without a hitch, to the song "Winter Wonderland". Frosty, Crystal, and Jack have fun with the children all winter, but they notice the weather is starting to grow warm again. Jack decides to make it so that winter lasts forever and Frosty and Crystal can stay. As the overly long winter continues, Parson Brown decides to talk with everyone. He tells them that winter will never last forever, if winter lasts forever the trees will never sprout leaves and flowers will never grow. Frosty, Crystal, and Jack once again head for the train to the North Pole. Frosty and Crystal say their goodbyes to the same traffic cop Frosty encountered in the first special, who wishes them away only to swallow his whistle in shock again when he hears he has married. All traces of winter melt away, but everyone remembered that the winter wonderland was a good memory and good memories can never die, so the narrator said. Because everyone knows that on one not so faraway day, that first snowflake will fall. The scene then shows Jack Frost up in a tree. And in a few months, the whole town becomes a winter wonderland again. The special ends with the narrator saying to the viewers, "May all your winters be wonderful." And Frosty and Crystal responding, "And frosty, too!"
The rights to this special are held by Warner Bros. Television Distribution, which licenses the show to Freeform. The latter airs the special annually on its "25 Days of Christmas" marathon. In 2018, AMC took over the license for the special. Because the ownership of the television rights to the Rankin/Bass library was split into two parts after the company's dissolution in 1987, Frosty's Winter Wonderland was separated from the original Frosty the Snowman special. The telecast rights to the original are now held by CBS, who produced a companion sequel of its own, Frosty Returns, with a totally different cast, style and production staff.
