Weren't the space horses in the Canto Bight side quest in TLJ? I've blocked most of RoS from my mind. I understand the criticism of TLJ, but it took chances, particularly regarding The Force, that were novel in the film series (perhaps they had existed elsewhere), such as the idea that The Force could "belong" to anybody (e.g. Broom Boy). Everything that made TLJ interesting (also the stuff that made the fanboys hate it) was abandoned. Instead of Rey being an "anybody", which was set up beautifully by TLJ, she was somehow a descendant of Palapatine? Good grief. And now the Skywalker name is part of the Palapatine genetic line? Double good grief.
