Years have passed since Frosty left for the North Pole. When he hears about the first snowfall of the season, he decides to return. The children are overjoyed when Frosty 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 about Frosty and his magic hat which brought him to life, he decides to steal it from Frosty so the children will love him more. But that night, while Frosty and the children are ice-skating at a frozen pond, Jack unknowingly captures a horse's hat with his ability to blow snowy winds. Believing it to be Frosty's top hat, he disappears with it.
Despite the fun he has, Frosty feels lonely when the children go home each night. To cheer him up, the children, build him a snow wife to keep him the next day and they name her Crystal, but the group cannot find a way to bring her to life. Late that night, Frosty presents Crystal with a bouquet of frost flowers, and his gift of love brings her to life. Just then, Jack uses a gust of icy wind to blow Frosty's hat off, rendering him lifeless. Crystal makes a corsage out of snow, places it on Frosty's chest and gives him a kiss, bringing him back to life. Befuddled by Frosty's reanimation, Jack throws the hat back onto his head.
Frosty and Crystal run through the town and announce their wedding plans to the children. Parson Brown, the local preacher, assists the children in building a snow parson whom he brings to life with his Bible. When Jack tries to spoil the wedding with a blizzard, Frosty and Crystal reason with him and ask for him to be the best man at the wedding. Jack agrees, and Frosty and Crystal are married.
Frosty, Crystal, and Jack have fun with the children all winter, but they notice the weather is starting to grow warm. Jack uses his powers to extend the winter, but after Parson Brown warns them about the dangers of everlasting snow, the three decide to return to the North Pole. They skate to the train station and bid farewell to the children. Months pass, and the land becomes a winter wonderland again.
Because the ownership of the television rights to the Rankin/Bass library was split into two parts (one including all productions prior to 1974 and one including all productions from that point onward) after the company's dissolution in 1987, Frosty's Winter Wonderland was separated from the original Frosty the Snowman special. As a result, CBS, the longtime broadcast rights holder to the original special, produced a companion sequel of its own, Frosty Returns, with a totally different cast, style and production staff. Today, the broadcast rights to the original are held by NBC, a sister company of the pre-1974 Rankin-Bass library owner, DreamWorks Classics.
