Where I used to live, there was an island with wild horses that would swim to the mainland occasionally (there was an actual event for this, but I'm not talking about that). You'd just be chilling on the beach, having a good day, when suddenly, a horse appears. It uses confusion. It is super effective. Everyone stares at it as it walks out of the waves, shakes like a dog, and then trots off. Very nearby was a pretty rural area, and anyone with horses in that area would tell stories about the island horses straight up stealing their horses, and them having to talk to state wild life department about it and get their horses back from the new wild horse's roving harem nearby in one of the swamps.
