The fisherman under the Great Bridge is trying to catch the kappa. Get the rotten fish from the Fortress steps and you can lure the kappa. Aim the beehive to block the tree hole, roll the rock over the right side hole, light the campfire, which fires up the paper lantern. This will force the kappa to enter through the lily pad holes, and the frog can block all but the center hole where your net is. Click the fish to place it on top of your net.
