They are capsules, like a whole corn kernal, except they are not corn kernals. They are about the size of a pea but very oval, opaque and translucent. I squeezed one in, in paper towel and it popped a liquid, I didn't notice anything else. Some looked like deflated capsules. I've only noticed the ones that float. Are these eggs of some sort? They've been coming out with warm water enemas. Any ideas what this may be?
