Crab Corral?

Over the last little while we've been talking about what type of lasting impact taking the boys around the world would have. For example, we've wondered how much the boys took away from our adventure to Europe. Well, during our trip to Hamilton Island we found out.
We had hiked into a secluded beach at low tide to find a whole range of sea life exposed to view, and, unfortunately for some, to touch. There was lots to see--hermit crabs, coral, sea slugs, clams, rock crabs, etc.
The boys were drawn immediately to the hermit crabs. They ran around the beach for a couple of hours collecting all shapes and sizes of crabs. I asked them what they were doing with them and they promptly responded that they were creating a crab corral to house them all. Interested, I walked over to see the newly constructed corral.
One look revealed that one person's crab corral is another person's crab colosseum. It was an exact replica of the one they saw in Rome complete with arena and staging area. They filled the arena with hermit crabs and then introduced other sea life to see who would survive the encounter. I guess some experiences have lasting (and maybe degenerating) impressions.
