Animation
Clarabelle first appeared as a farm cow in the cartoon Plane Crazy in 1928.[5]. She appeared frequently from 1930 to 1932 and less frequently afterward, making her final classic-era bow in Symphony Hour (1942)[6]. As with most Disney characters, she was given small cameos in the featurettes Mickey's Christmas Carol (1983) and The Prince and the Pauper (1990), and the 1988 feature Who Framed Roger Rabbit.
Clarabelle mostly played bit-part characters in the approximately 30 cartoon shorts in which she appeared, and her character was never as fully developed as Mickey, Minnie, Goofy, Donald Duck or Pluto. She and Horace Horsecollar had an uncanny ability to change from somewhat normal farmyard animals into anthropomorphized beings as necessary. Apparently Clarabelle was given a skirt originally to give a modicum of modesty to the rubbery bovine, serving to hide her enormous appendage.
In modern animation, Clarabelle has returned to active use, appearing first in a few segments of Mickey Mouse Works and in a brief scene in Mickey's Once Upon a Christmas. In Disney's House of Mouse she regularly turned up as a gossip columnist, with the tagline "Gossip is Always True". Recently, Clarabelle has also made appearances in the preschool series Mickey Mouse Clubhouse (in which she owns a puppy named Bella) and in the direct-to-video movie, Mickey, Donald, Goofy: The Three Musketeers as Pete's lieutenant and Goofy's love interest. Clarabelle also makes a cameo in Kingdom Hearts II in the Timeless River world as one of its citizens. Clarabelle is a playable character in Disney TH!NK Fast.
Disney theme parks
From September 2006 to September 2008, Clarabelle Cow and Horace Horsecollar appeared together for meet-and-greets in Town Square at the Magic Kingdom in Walt Disney World. Also, they were in the Main Street Family Fun Day Parade. Since Family Fun Day's ending, the two haven't been easy to see outside "Mickey's Boo-to-You Halloween Parade", "Mickey's Once Upon a Christmastime Parade" and the occasional special event.
Clarabelle also appears (without Horace) at
Disneyland Park. She has also appeared in several Disneyland parades and shows over the years, including The World According to Goofy, Light Magic, the Parade of the Stars, Fantasmic, A Christmas Fantasy Parade and Celebrate! A Street Party. Clarabelle and Horace come out for meet-and-greets and appear in parades and shows on a regular basis at Tokyo Disneyland as well. In 2009, Clarabelle played a leading character in the New Year's Greeting at Tokyo Disneyland and Tokyo DisneySea.
They sound a lot like my first moments- awe, shock, joy, rapture, etc... 
The pictures of the boys with Mickey are so cute, they look so little! 
The boys were so little! I barely recognize Koby! They were just as cute then as they are now, though!
