Emek found 6 stepping stones beside the forest path, and Luna found 3 more near the stream. They placed all the stones in the water to make a safe path. After trying the crossing, they noticed 2 stones were too close together, so they picked them back up and moved them to a better spot. Then they counted the stones in the stream again, smiled at their sturdy bridge, and safely crossed to the other side.
