Easy coins

When Ben tells you to use the metal detector to locate the Gopher's coins, go to the barnyard. On the right side of the farmer's house you will see yellow flowers. Use the metal detector to find a group of coins. At night, go in and out of the party. Each time you use the metal detector on the side of the farmer's house you will get more coins.
