Hi there, ariche503.
The version you're thinking of is the hourlong version of "Mickey's Christmas Carol" that contained the 1983 short and the three bonus cartoons that you mentioned. This aired annually on TV in the 80s and 90s, before Disney bought ABC. Our family has a copy from 1986, which also includes my brother's christening as well as the Corazon Aquino/Fernando Marcos "Nightline" appearance from earlier in the year. According to wikipedia, "The Art of Skiing" was cut out of broadcasts starting in 1993, and eventually the hourlong special was reduced simply to "Mickey's Christmas Carol" on its own.
Unfortunately, there have never been any VHS (to my knowledge) or DVD releases of the four shorts together. Usually "Mickey's Christmas Carol" is paired with "Pluto's Christmas Tree" but they haven't yet been paired on home video with "Donald's Snow Fight" or "The Art of Skiing". The list below refers only to DVD, I'm not sure of the VHS releases.
Pluto's Christmas Tree
and Mickey's Christmas Carol
- both are available in "Walt Disney Treasures: Mickey Mouse in Living Color, Volume Two", "Classic Cartoon Favorites, Volume Nine: Classic Holiday Stories", "Walt Disney Animation Collection, Volume Seven: Mickey's Christmas Carol", and the two DVD releases of Mickey's Magical Christmas: Snowed In at the House of Mouse
Donald's Snow Fight
- available in "Walt Disney Treasures: The Chronological Donald, Volume Two"
The Art of Skiing
