Horsey is Cleveland's pet horse in "The Way the Cookie Crumbles".
When Cleveland spots a horse trailer go by with a sign reading "horse for sale", he decides to buy the horse. Cleveland plays with the horse while his father LeVar Brown does chores. Horsey tripped over a washtub left out accidentally by LeVar while playing frisbee and broke his leg, needing to be put down. Cleveland had his father dig the grave, lower Horsey into it and then fill the grave.
