An couple of interesting scientific tidbits about sucker demons and the nature of their electric properties: When I pinch one really hard (say, if it slithered into my bed, which is usually what they do) while I'm holding my cellphone, it will vibrate, as if a call is coming through, and the screen will dim as if malfunctioning, and then go black. Or, if I'm holding my laptop, the screen will shimmer. Sometimes, they actually shock me, which is rarely painful, but can be.
