Welchenos galumphed along the beach, trailing a length of seaweed and a piece of bark on which were piled various types of shells, rocks, and anything else an enterprising young cub could find along the beach and make off with. There was also one unfortunate crab that kept climbing off the pile, causing Welchenos to stop, herd it back on to the bark, and take off again as the whole thing was repeated. Eventually he came to a small pool, evidently dug by himself, that was filled with water by means of a trench leading into the sea. He busied him self filling the trench with sand so no more water could come in (re-herding the crab several times in the process). Once everything was set up to his satisfaction, he started picking up some of the treasures on the bark and tossing them into the little pool, one by one, and watching what happened.
