Blueberries are a kind of berry that is small in size and blue in color. It is generally considered the primary source of nutrition for the Smurfs along with sarsaparilla leaves, squash, and smurfberries.
In the 2021 TV series, episodes such as "Clumsy Not Clumsy" and "The Pluffs!", it is revealed that blueberries have replaced smurfberries.
In the Smurfs 2011 film and Smurfs: The Lost Village, the blueberries are referenced as "smurfberries".
Blueberries are also plants in the game Smurfs' Village that take the shortest time to plant, as they only take 30 seconds, and are currently the only free crop in Game. They are (except for Sarsaparilla, which never wilts) the only plant that doesn't wilt in the time it takes to grow them, as it takes 5 minutes instead of 30 seconds.
