These two together are either in complete agreement or complete disagreement.  Double trouble.  In the sand it was mostly complete agreement.  But occassionally there was an issue over a shovel or a disagreement over a sand castle design.  But they could walk along the beach and pick up sea shells (and rocks) like the absolute best of friends.

And in the water they worked on catching waves while on their bellies (which likely explains the tiny sand particles I can't seem to get out of their swim suits.)

So while they may look all sweet, they can definitely be double trouble.
