Pia and the Blue Mushroom

Find Pia in map.

Under the watchtower in map, you see Pia, wearing a teddy bear costume. How cute! She tells you that she ran into a bully Blue Mushroom on her way to map, and now she wants you to show the rude mushroom who's boss! Collect 20 Green Mushroom Caps and 20 Blue Mushroom Caps as proof. You contemplate telling Pia she's asking to be teased, walking around the forest in a bear costume, but you decide against it.

You delivered 20 Green Mushroom Caps and 20 Blue Mushroom Caps to Pia in map. She was thrilled that she got vengeance on the mushrooms and gave you a Scroll for hat. All you have to do is click on it in the Use tab of your Item Inventory and drag it to your helmet in the Equipment window... Oh, and you'll have to cross your fingers and hope the Scroll doesn't fail.
