Not all Pixies are female, but those are the ones that always seem to get on TV. Though very diminutive, Pixies are not to be trifled with...because they will "mess" you up. They have a very weird scream when they get kidnapped.
Spud tried helping a Pixie in trouble. Jake told Spud to be careful with the Pixie because she was a little riled up. Spud told the Pixie not to worry, but the Pixie bit his finger. Spud then tried shaking the Pixie off, but Jake told Spud to watch it because if Spud shook the Pixie too much, she'd get sick.
