Ok, this is rather silly. But people have made LEGO mechs piloted by frogs before, so I’m in good company.
But I don’t think I’ve ever seen a battle mech piloted by a horse before.
I said once before that I’ve had a long-standing ambition to use the horse element in a spaceship, so perhaps this is where the inspiration came from. But I really have no idea. Just another of the weird ideas that pop into my head.
