Dark red blotches over the body are usually petechiae which are caused by bleeding under he skin. This is normally caused by a lack of clotting factors sometimes because of an underlying condition or more commonly, ingestion of a toxin such as rat poison. It could also be due to a rash. I would take Mcfly to the vet to get this checked out because it could be a sign of something serious. Even though he is bright it could be an issue in the early stages. Hopefully it is nothing but best to be safe.
