Prattles

Prattles are an Elven candy, a sweet, caramel chew that comes with a collectable pin. Sophie Foster was introduced to these candies by Dexter Dizznee, which he gave her one after they licked their DNA locker slips at Foxfire.

Pins (Spoilers)
Prattles pins are collectable, one made for every known animal alive. For example, by the time of Exile, there was only two Alicorn pins, making them the rarest pins ever. The Black Swan frequently uses them as clues for what Sophie should do next, one time giving her a pin made from a certain metal that she could use to bottle Everblaze. Sophie is known to posses the first of two Alicorn pins, given to her as a clue from the Black Swan.
