Scooby Doo Mystery

Scooby Doo Mystery is a point and click adventure game starring Shaggy and Scooby Doo.  The game has two locations with their own mysteries to solve: Blake's Hotel and the Ha Ha Carnival.

There is also a game with the same title for the Super Nintendo Entertainment System, but it is a completely different game made by a different developer that is a platformer instead of an adventure.
