Warning Issued on Popular "Smurfs" Game

(CBS/AP) Listen up, parents! "Smurfberries" cost real money -- but you might already know that.

The publisher of the popular "The Smurfs' Village" game for the iPhone and iPad recently added a warning that virtual items, such as Smurfberries, aren't free.

An Associated Press story earlier this month revealed that parents have been surprised by charges racked up by their kids in games such as "Smurfs' Village." The games are free to download but allow in-game purchases of virtual items like Smurfberries. Just two taps can buy $100 worth of Smurfberries.

Capcom Entertainment Inc. updated the game Sunday. When the game starts up for the first time, a pop-up now warns about the option to purchase Smurfberries and that charges come out of owners' iTunes account.
