Go to the oasis in Krok. Go down to the well. Now go to the left, between the two buildings. See the darkened portal? Look at the two totems on either side of it. There are five lights that need to be lit up the poles. They take about ten minutes each. About once per hour, the portal will light up. Jump on it. It will take you to a secret shop. The items are not great, but if you run back and forth in front of the clothes rack, you will get a Secret Shopper badge. :O)
