Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Brainy is very knowledgeable in the study of biology, though his knowledge is only second to that of Papa Smurf. In the mini-story "The Smurflings' Biology Lesson", Brainy tries to teach the Smurflings the parts that make up a Smurf's body, but is constantly harassed by Snappy Smurfling's remarks which amuses his fellow Smurflings.
