The Rankin/Bass versionEdit
At the beginning of the original 1969 special, Frosty is built by Karen and her friends right after school has closed for Christmas vacation. The wind blows the hat of Professor Hinkle onto Frosty's head, and suddenly the snowman comes to life, saying his cheerful catch phrase, "Happy birthday!" Frosty is good-natured and playful, but also somewhat naive due to his relative youth (having just been "born"). He is unable to count above five and is the world's fastest belly-whopper.
Frosty has two physical weaknesses: the tendency to melt in warm weather, and the hat, without which he becomes another inanimate snowman. (However, when Frosty gets startled by the Traffic Cop and later by the ticket man, his hat briefly jumps off of his head. Also, in Frosty's Winter Wonderland, he is shown lifting his hat off of his head twice.) Karen and her friends offer to help Frosty get to the one place where he could never melt - the North Pole. However, Professor Hinkle chases after Frosty and Karen, trying to steal his hat back, and eventually traps them in a greenhouse. Fortunately, Santa Claus manages to revive the melted Frosty by letting in a December wind and afterwards takes him to the North Pole.
Frosty promised to be back again someday, and in Frosty's Winter Wonderland, he fulfills his promise. The character's design is only slightly altered from his original appearance, primarily the addition of a scarf. As much as he enjoys playing with the kids, Frosty becomes lonely when they have to return to their homes. To remedy this, the kids construct a snow-woman, who Frosty names Crystal. She comes to life when Frosty presents her with a bouquet of flowers, a gift of love. Despite the interference of Jack Frost, who attempts to steal Frosty's hat out of jealousy, the couple are wed by a snow parson (and Jack is mollified when asked to serve as best man).
Frosty appeared in stop-motion animation in the movie Rudolph and Frosty's Christmas in July. By now, he and Crystal have two snow children, Chilly and Milly (the means by which snow people procreate is ignored; possibly, they simply built their own children out of snow). In this production, Frosty is best friends with Rudolph, who serves as adoptive uncle to the children. Frosty and his family accompany Rudolph to an unnamed American town, protected by amulets provided by the evil Winterbolt.
The pair generally enjoy their time performing with Lilly Loraine's circus. But when Rudolph is tricked by Scratcher into giving the circus's money to Sam Spangles and his nose's light goes out as a result, Frosty comes to his friend's aide, offering to sacrifice his life in exchange for helping Rudolph and protecting his family by giving up his magic hat to Winterbolt. The evil wizard betrays him, but Rudolph is able to retrieve the hat. To celebrate, Frosty and Rudolph sing a variation of "We're a Couple of Misfits" (from the original Rudolph the Red-Nosed Reindeer special). Frosty and his family eventually do melt after Winterbolt is destroyed, but they are brought back to life by Jack Frost, and they return to the North Pole with Santa.
Appearances in other Christmas mediaEdit
The Rankin/Bass version of Frosty made a guest appearance in the comic strip FoxTrot, in a storyline that ran from December 16-21, 1996 (reprinted in the collection Come Closer, Roger, There's a Mosquito on Your Nose). Here, he appears in a dream of Paige's ("You were expecting Freddy Krueger?"), in which he takes her to the Land of Animated Christmas TV Specials to cheer her up when a hard homework assignment puts her through much stress. A later FoxTrot strip, published December 5, 1998, has Jason watching the Rankin/Bass special and reacting to it as if he were watching a horror movie.
A parody of the Rankin/Bass Frosty makes a brief cameo in "A Very Special Family Guy Freakin' Christmas", where he is quickly burned and melted by an irate Lois Griffin.
The Legend of Frosty the Snowman features Bill Fagerbakke as the voice the Rankin/Bass version of Frosty. (Coincidentally, Bill Fagerbakke had previously voiced a parody of Frosty, played by Patrick Star, in the Merry Nickmas short "Patrick the Snowman".)
- Disney featured a costumed version of Frosty in the Magic Kingdom Yuletide Special.
- Frosty Returns, an unofficial semi-sequel to the original Rankin/Bass special, features John Goodman as the voice of Frosty, who this time concerns himself with the effects of environmental pollution.
- Another parody version of Frosty, voiced by Clancy Brown, appears in Phineas and Ferb Christmas Vacation!, as a snowman that Perry the Platypus brings to life while on his way to his agency's Christmas party. He then walks off into the street and gets crushed by an offscreen truck. At the very end of the special, Perry fixes him back up, and he is about to walk into the street again, but this time decides against it when he sees a truck smash into a vegetable stand.
