I really don't think it is froggy doo, I have cleaned up lots of that and have never seen any look like that in the water or out. I would rather wait and be sure than throw out a baby... just won't tell anyone I took care of it if it is just a perfect poo! LOL. It looks like the pictures of eggs but it seems to be missing that clear part that surrounds the egg. I did see frogs mating a week ago. Guess I'll keep an eye out for more of these mysterious round shape retaining poos/babies. Do they call only during mating season? Two of mine seem to call every night.
