I need asap. Oh, and he is a show jumper.
Just use his normal name. You don't need anything fancy for a small show.
Ok, well look into some real show horses and see what they are called. You could do a spin off on one of those names. I think it needs to come from you really, something personal.
I am very sorry to say this but he looks more like a foal
He kinda does. But he's not. Do you have any show names for him?
