Scooby-Doo, Where Are You!
While en route to the museum to deliver the Black Knight armour, Prof. Hyde White was kidnapped and through an elaborate scheme by Wickles and his colleagues, he was gagged and bound the professor underneath the Indian effigy on display at the museum because he would've spotted the art forgery that was taking place there. He could only watch helplessly as the gang made their investigations there while trying to solve his disappearance. When Wickles's plot was uncovered, Prof. Hyde White still hadn't been found until Scooby-Doo found a shoe which led to discovering the professor under the Indian effigy.
