This is Episode 18.During clamming season, Atsushi Miyazawa gave Pankun a clam digging mission instead of shopping and buying thing as he would normally did.Pankun use 600 yen to buy an entrance ticket. This cause him unable to buy the rain boots, fortunately he can still rent it with only 400 yen. Pankun though he bought the rain boots with 400 yen, it seems he didn't understand what is renting.When digging, Pankun didn't have much luck initially but luckily he stumble upon a blue rain boots and 2 hidden clams. Usually when you found 1 clam on a spot, it means there will be a lot of clams sitting nearby.The rule is true and applicable even for a chimpanzee. No more empty shells and hermit crab !!---https://www.youtube.com/watch?v=jhsWy5EalWc
