Sometimes when you are walking your dog you will find a sign on the side of the road. it has a picture of a mii walking a dog over a green field, and it is called the secret path. It is unlocked early on in the game right about when you get the rainbow afro at Mr. Recycle. On the Secret Path there are tons of presents some hidden in the grass, and others in plain sight. Rare items can be found and even the other miis walking their dogs give rarer presents then usual!!! The secret path can be found anywhere on the walking trails.
