I looked for a pig to go in my Astro Hog several years ago. Very little was available. My brother eventually found a pig head at a dollar store. It was a "grabbing stick" of some sort. The pig head was hinged at the jaw and the mouth opened and closed to grab small objects. It could pick up something like a marble or a small piece of candy. He cut the head off of the stick and glued him to the cockpit floor.
