EquiReal horses are animated, lifelike riding horses that are worn as attachments, so they don't count against your prim limit and can be ridden anywhere, any time. Expert modelling and scripting make for smooth, realistic and above all believable animation whether you're walking, running or jumping. Easy to use HUD buttons let you control features such as sounds, hoof prints, dust, rearing or... fertilizing the roses.
