Scooby-Doo impostor (Homeward Hound)

The Scooby-Doo Impostor was the disguise of M'Lady Moonbeam, a smaller dog wearing a suit with stilts. She was helping her mistress, Meadow, to kidnap the Secret Six puppies from a dog show.

Physical Appearance
The physical resemblance to Scooby-Doo was perfect, other than having no collar and a harsher expression.

Personality
The impostor could not talk, and was much fiercer than the original. This gave the game away to Shaggy Rogers.
