Mr. Dr. Professor Patrick
Developer of Awesomeness
The voice of Purankuton (プランクトン), the Japanese Plankton, has a female voice if you didn't know. The only exception is in the first SpongeBob movie, where he has a male voice. In SOoW, though, he has a female voice once more.
I may be wrong about this, since I learned this after asking my Japanese professor (if somebody knows any better, let me know!). In Japan, the Japanese tend to think that small things must have small tiny voices, so they probably gave Plankton a girl's voice to emphasize how small he is. In other words, it's a cultural change.
Either way, it's hilarious to watch Plankton with a little girl voice trying to steal the secret formula.
