The following was published on my 'Harvest Moon Forever' site last month but as players tend to visit one site and not the other, it probably needs to be added to this site as well. Remember always that the most up-to-date version of any information about this game should be found in my General Guide.
Winter in Harvest Moon games always tends to be quite different from the other three Seasons but Winter in Grand Bazaar has some very creative additions to the usual snowy landscape.
First of all, there are snowballs on the ground and although you cannot push them together to make your own Snowmen who speak and give you gifts as you can in Animal Crossing, they often DO contain Gifts from Nature. Throw the Snowball to smash it and you may find it contains an Ore Stone or other surprise, including Cooked Dishes and Flowers from every Season. Freyja found a Curry Dumpling in a Snowball on the second day of Winter, Moondrop Flowers and Magic Blue Flowers. As the season progressed, she found all other Flowers in Snowballs. If your Character does not use them as Gifts, he/she can make Flower Perfume from them. Winter is the best Season for this unless you are involved in Multiplayer Sessions where you can purchase Flowers from other Seasons from players. Remember that no Flowers or Insects will be found on the Map during a Multiplayer Session, although Fishing in the Host's current Season is possible once you have a Fishing Rod.
Incidentally, there are Snowmen of various sizes and designs stashed here and there throughout the Map, although I have yet to receive a visit from one on a snowy night as in Animal Parade, asking for a replacement for his lost nose.
Next, although the River is frozen in Winter, you can find cracks in the ice. Use your Hammer to strike the ice where you see the cracks and it will create a large hole where you can dive for items or fish. Despite the freezing temperature, your Character will react no differently to immersion in the water in Winter...
Ore Stones can be found on the ground in Winter as well as inside Snowballs and when diving in the River.
There are two kinds of sparkles in Winter. One is the sparkle of ice that can be found randomly anywhere on the map, including locations your Character could not possibly reach. These are 'eye candy' in the form of glittering ice from Winter's freezing temperatures. The othr sparkles are the usual ones that denote the presence of coins.
So far, the only Cooked Dish I have found inside Snowballs is Curry Dumpling. The Rank/Quality varies, however, making one Curry Dumpling worth more than another. A Snowball incidentally can contain another Snowball!
A new activity in Winter is Snowboarding. Mayor Felix will deliver a Snowboard to your House on the 2nd of Winter or thereabouts and announce that there will be a tournament on the 20th. You can practice on the course on the Hotel Screen. Once the Snowboard delivery occurs, you will find a Skateboard on sale at the Bazaar for 9000G. This appears to take a slot ordinarily devoted to one of the Pet Toys. The other Pet Toy will continue to be sold. I believe that the Pet Toy is chosen randomly but if you wish to make certain that both are sold at Felix's Stall, you probably should purchase the Skateboard and be done with THAT.
Amir will be introduced in the first Winter on or about 3 Winter by Mayor Felix and will stay at the Hotel. Milk makes him very happy. All likes/dislikes as well as the schedule of Amir's Heart Events can be found in my Courtship and Marriage Guide.
