The Katniss effect is going strong over at Nerf where the traditionally boy-oriented company will be introducing a new line of pink crossbows and accessories under the Rebelle name this Fall. The coolest among them is the Mission Central App Cradle ($15) that can be attached to the Heartbreaker Bow ($20) or the Crossbow ($25). The cradle holds an iPhone that, when using the free Rebelle Mission Central app, allows kids to join together (virtually) to compete as squads. They can create their own avatars, accessorize them, and then play games (and win prizes) in those characters. It's one of the first toys encouraging girls to do so.
