The ocean beach was very different from the Lake Michigan beach that he's used to. The waves were much bigger and stronger, and the sand was covered in seaweed and a hundreds of tiny seashells, rather than just the smooth rocks that wash up at the Indiana dunes.
He mostly played in the sand in the beginning, and eventually worked up the curiosity to venture out to the water. However, once he got out there he became aware of the loud, crashing waves and decided to head back to the safer, quieter shores. I can hardly blame him - the waves were strong enough to send me doing flips underwater, so I'm sure they must be pretty intimidating to a two-year-old.
"He is wise in heart, and mighty in strength... Which alone spreadeth out the heavens, and treadeth upon the waves of the sea."
