HELP! 10 PTS!!!!! What is the episode with Scooby Doo talking about Worcershire Sauce?

I've been looking for years for this episode but cant seem to find it. last time i watched it I was 3 or 4 years old, so a REALLLYYYY long time ago. If i can remember correctly, the episode where Scooby talks about Worcershire sauce involves the villian blending into walls or his surroundings, like a chameleon, and he hates worcershire sauce but scooby LOVES it. If someone could just tell me where to find this episode that would be GREAT!!!!
