Go and talk to the fisher. He will take credit for your work.
You catch the Kappa fish under the red bridge. On the right side of the bridge, there is a set of stone steps. Go down and then left. You will see a man on a boat. Talk to him about the Kappa.

Move the boulder on the right side. Shoot the bees at the hole in the tree. Put the frog on the lily pad with bubbles under. Click the logs to light up the lantern. Click on the rotten fish then you can catch the kappa. (No reward in return.)
Go to the east EDO and talk to the man by the fish and squid shop. Ask him about basho he will say you'll have better luck catching the kappa and will give you a rotten fish. Then use it to catch the kappa.
