I think they mean that, for example, you have a picture of a stationary Stickfigure

People would take pictures of each limb and make them into seperate sprites, then they could combine each sprite/limb together, and now it’s “rigged”, so you could move its body parts seperately

I disagree

Plain chicken tenders are superior. In fact, all foods without dressing or toppings are better off without them. With the exclusion of things like Salt, of course.
