Casper's First Christmas was a 1979 half hour holiday special produced by Hanna-Barbera that might be a Christmas tradition for a lot of fans. However, it is also one of the stranger examples of a Crossover.
In the special, Casper the Friendly Ghost and Hairy Scary are not in the future like Casper and the Angels but a modern time. Living in a rundown house (set for demolition) on Christmas Eve, who would happen to show up but Yogi Bear and friends?
Followed a year later by Yogi's First Christmas, despite Yogi and friends already knowing about and celebrating Christmas in the Casper special. Yogi and the rest of the gang would also return for more seasonal hijinks in 1982's Yogi Bear's All Star Comedy Christmas Caper and (in much younger and abjectly hipper form) "Santa Claws!", the 1991 series finale of Yo Yogi! Two decades after Hanna-Barbera and Casper parted ways, Casper would star in the 2000 straight-to-video film Casper's Haunted Christmas, loosely based on the 1995 feature film's continuity.
This cartoon provides examples of:
- Animation Bump: While an overall marked improvement from HB's usual output due to being a one-off, the musical numbers are far more fluid than the rest of the special.
- Christmas Carolers: The characters make merry by singing.
- Christmas Episode: Counts as one for most of the shows involved.
- Crossover: Casper and Hairy Scary of Casper and the Angels meet up with Yogi Bear and Boo Boo from Yogi Bear, Huckleberry Hound from The Huckleberry Hound Show, Quick Draw McGraw, Augie Doggie and Doggie Daddy and Snagglepuss
- The Grinch: Hairy Scary is not a friend of Christmas.
- Haunted House: Well, the setting house totally has two ghosts living in it.
- In the end, Santa turns it into Hairy's Haunting Lodge.
- HeelFace Turn: While Hairy isn't that bad, he still turns from Scrooge to friendly by the end of the special.
- Prequel: More than likely, it's one to Casper and the Angels.
- Santa Claus: Ho Ho Ho, he shows up too.
- The Scrooge: Hairy Scary doesn't want to celebtrate Christmas.
- Shout-Out: Inside the house there are cameos of two mice that resemble Pixie and Dixie from Pixie, Dixie and Mr. Jinks. Perhaps their parents.
- In addition to The Scrooge above Huckleberry asked Hairy if he's "the ghost out of Dickens"
- Wrong Turn at Albuquerque: Yogi took the wrong directions to the ski lodge that he and his friends were supposed to be going, and they wind up at the abandoned shack where Casper and Hairy happen to live.
