Suffolk Sheep are available in Sunshine Islands.
These high quality sheep will only become available once you ship your first piece of S-rank wool. Once a sheep wins the Sheep Contest, it will start to produce s-rank wool.
Mirabelle sells Suffolk Sheep for 12,000G each. Although expensive, they will produce better quality wool. The wool from a Suffolk Sheep is worth more then double what regular wool is! Instead of every 3 days, Suffolk Sheep can only be sheared every 6 days. Brushing sheep with the Brush will increase their friendship and their wool quality.
If you use a Miracle Potion on a sheep, the sheep must not be sheared for the potion to work. A sheep will give birth in 16 days, and it will take another full 16 days from the birth for a sheep to be full grown. Sheep will live for approximately 5 years if they are properly cared for.
