When you're dealing with the Pokemon equivalent of the Grim Reaper, you know you've got a real creepfest on your hands.
Duskull, a Ghost-type Pokemon, kidnaps disobedient children and is said to love the sound of their crying.
It also has the ability to pass through walls and turn invisible, which helps as it "doggedly pursues its intended victims until the break of dawn."
Hmm. Remind us to mention Duskull the next time our kids don't listen, wouldja?
