The day the boys stood still is the seventeenth episode in the first season of Lucky Fred.
Brains sees no interest in Fred's new passion: 4x4 Mud Racing. For his part, he asks Friday to turn into an all-terrain vehicle in order to compete. Unfortunately, during the race, the noise awakens the demons of mud.
- First appearance of the Dirt Demonds.
- This episode reveals that Brains has a "Intergalactic Driver's License" from the academy, when she was seven.
- Dirt demons are possibly a reference to "the Magmanamus" from the "Dexter's laboratory" cartoon.
