Class is in session with Grandpa Smurf as he teaches Sleepy, Brainy and another Smurf student all about Smurf history with the Schoolin" Smurfs by Mega Bloks. Build and rebuild the Smurfs classroom any way your little Smurf fan wants so Grandpa Smurf can teach at the front of the class. All three young Smurfs are always ready for school, but the trick Grandpa will have to learn is how to keep their attention.
