Chocolate Frog (plastic) from Half-Blood Prince US Premier Party Gift Bag. This prop given out to a lucky few at the Premier Party.
The premier is the first showing of the film where the stars walk the red carpet. After the US premier, they held a party for the cast and other people who attended the premier.
At the party, gift bags were given out. This plastic chocolate frog comes from one of those gift bags. :)
