[... "what's a fairy"? Link doesn't think he's ever met someone who didn't know what a fairy is before. Maybe people who hadn't seen one, at most. Link stares up at him in surprise.]

They are... forest spirits. They're small, [Link tucks the mask away into his pack so he can hold his hands up, using his fingers to make an approximation of the average forest fairy. Teeny tiny.] And they glow. There are lots of different types, like the guardian fairy, which are this big. [He moves his fingers apart to a bigger size.] They are assigned to Kokiri to be their partners. You can see the wings on guardian fairies, because they have four of them that are long.
