Original Airdate: September 21st, 2000
US Airdate: September 29th, 2001
Caught in a sudden thunderstorm, our heroes quickly seek shelter from the elements at an ominous looking castle on a nearby cliff. Although this seemingly vacant fortress is a little on the spooky side, Ash, Misty and Brock would rather be jumpy than soggy. That is, until they hear moaning coming from a nearby corridor! Follow our heroes through the pitfalls and mazes of this (haunted?) house on the hill!Tropes
