This cute little Hippo was exclusively available at the 2010 San Diego Comic Con, and through HasbroToyShop.com at the same time. It is brand new in box, and guaranteed to be authentic, as I purchased it directly from Hasbro's website in 2010. (See last photo for a screenshot of original order confirmation email.) 

The box does have some wear from years of storage. The front of the box is squished in at the very bottom where the tape is. There is also some wear on the edges and corners, some small marks and scratches, and several spots where the color has come off.  The clear plastic has a lot of light scratches and small scuffs. The hippo inside looks great, and is still held firmly in place.
