Sometimes horses can randomly end up with a rare and unique pattern! These Somatic Mutations can occur in any breed on Horse Fable. They are not linked to a gene and so these patterns cannot be bred for. All foals born through breeding have a very small chance of being born with a Somatic Mutation. Wild and foundation horses can be generated with one as well. There are two types of Somatic Mutations per breed in Horse Fable. To see whether your horse has one, check the White Markings section of their page.
