Clone troopers are created in a cookie cutter way for a reason- they must live up to Sith standards and need to be physically able to crush insurrections in the name of the Empire.
Usually the clone creation process goes smoothly, but every once in a while a clone trooper comes out of the process acting a bit off.
You can tell when a clone trooper is only half baked by their tiny size and unusual fashion sense, as seen in this shocking footage shot by Rebel spies.
If you see one of these pint sized troopers in your squadron please inform your commanding officer immediately, or they might spread their silliness throughout the ranks!
