Clarabelle and Horace can often be seen in the Frontierland Hoedown at the Magic Kingdom.

I'm glad that these two awesome characters now appear to dance with kids in the Frontierland Hoedown (which most guests don't know exists), but in 2006 they appeared at the front of the Magic Kingdom to meet guests.
Those two had better appear for meet-and-greets at Pete's Silly Sideshow along with Minnie, Goofy, Daisy and Donald!
