SEASON 04, EPISODE 09: while playing outside one day, the kids lose their ball in a stranger's yard, which I'm sure you may already recognize as a common catalyst for witch encounters. They befriend an odd little girl who seemingly lives alone in the house with her fortune-telling grandmother, but of course, it's all part of an elaborate trap...
This is the most classic pop-culture witch you could ask for; a slimy green, hunch-backed, cackling old crone complete with a flying broom. She also controls flocks of ravens and hordes of black snakes, both of which are capable of "draining youth" for their mistress!
Though a backstory is given, it's not a sympathetic one - it seems to imply that there was once a real little girl with a real grandmother, but the soul of an ancient witch already possessed the young child, who subsequently drained what little lifeforce was left in her grandma as she set up operations in the old house.
