I have to give FuzzyRabbit COMPLETE credit for this one. He figured it out before I did.. (i tell you, i never do anything anymore…lol)
You can collect Spearmint Moss and Ullabulbs in Presto’s Edge and sell them for Coins to the rat cook in Explorer Camp. (Sorry I am horrible with their real names) Any way, I got 30 for the moss and 50 for the ullabulbs. You have to find more ullabulbs than moss. 1 of the moss is in a tree, you just run your mouse over it to collect it.
