I've solved all of the puzzles and found all but 1 pebble and 1 shell. Sunshower, I completely sympathize. I have babysat the heck out of it and can't seem to get either of these "rare" pieces to come up. I thought for sure that once I hit Level 3 Exploration it'd be cake, but nOooOoooo.... 24 hours later and still nothin'.
