The Triplets Season 8 Episode 2 Dr. Jekyll And Mr. Hyde

The Bored Witch punishes the Triplets by sending them to the dark, foggy streets of 19th-century London. There they meet Dr. Jekyll, who takes them on as assistants in his laboratory. But they aren't alone: living in the same house is Mr. Hyde, a frightening-looking and mysterious individual who stealthily leaves the house every night.
