Brainy Smurf is an important Smurf in the game. Whenever the player's Crops wither, he tells them, and asks them if they want to use a to make them ripe again. Besides that, he doesn't do much. Unlike Papa Smurf he doesn't give the player quests to complete, and he usually just walks around the village.
In story lines he explains things scientifically, and tries his best to help out the other Smurfs. Though some are annoyed by him.
- When a player clicks on him, he'll point out his finger, and grumble.
- Jokey Smurf likes to play pranks on him....a lot.
