Toby Terrier was a toy dog manufactured in the early 1990s by Tiger Electronics. The toy was designed to make various comments and remarks when placed in front of a television playing one of the select PLUS videos from the Toby Terrier and His Video Pals video series. In order for this function to work a specific cartridge that matched up with the video being played would have to be inserted into the toy. His collar contained a sensor that tracked what was going on in the movie. It was activated by pressing a button located below the sensor. The Toby Terrier video series was a comical and educational video series for kids, whose characters consisted of dog puppets. The video series itself was known as Toby Terrier and His Video Pals.
