[sb4] How would I go about multiplying a sprite, and making them move at the same time?

I think it has something to do with RND, but I don't really understand how to use it. Eventual goal is to produce a first game where you have to dodge these octopi; hit one and you lose (yeah, I know, real original, but it's my first game before I move on to what I want to do) If someone can please explain to me what to do, and how it works.
