How to challenge speedy sal

Answer from: Kinase
On the second island from the start screen (with the small island at the left) speedy sal will appear if you explore the corner at the right of that small island. Just explore, cut the trees and log out.

Answer from: Kallis Lena
At the second island, the one with the cove that has a small 1x1 island within it, Speedy Sal will appear in the cove if you clear the land due east of the 1x1 island, which is directly right from the right corner of that island. The land in the inner corner of the cove. I had land cleared on both sides of that too, so I do not know if that has to be cleared but he did not appear until I cleared that spot and went out of the game and went back in. Hope this helps. :-)
