 Spring Items
1. Edible Herbs: Found- Cave, area near the fisherman's tent
Selling Price: 30 gold Gift Rating (1-10): 2 These herbs taste good, and can be a snack. Since they only sell for 30 gold, it won't do damage to forfeit them for stamina. To find them, look around the fisherman's tent, and in the cave.
2. Veryberry Fruit: Found- Fisherman's Tent Area, Grove, Spring
Selling Price: 40 gold Gift Rating: 4 The Verrberries are found in many places. They are very popular with the vineyard workers.

4. Flowers: Found- Fisherman's Tent Area, Grove
Gift Rating: 9 Flowers are everywhere in the grove, and you can find some near the fisherman's tend too. They make really good gifts for all the girls, but specially Popuri. They can be found in summer as well as spring.
