Gruff's Groove Box (lost Nickelodeon music series; 2001)
Gruff's Groove Box was a music series that aired on Nickelodeon in Southeast Asia, South Korea, and some other territories (at least one site claims the show aired in Australia and was featured in their Kids' Choice Awards).
The series revolved around a claymation dog named Gruff and his inhouse band called Kitty Litter. They took requests on music videos to play, read fan mail, and interviewed celebrities.
The series is perhaps most remembered for being yanked off in the air in Malaysia due to the death of the king just one day after its premiere. (A law in Malaysia bans all upbeat music from being played for a month after the king's death.)
No footage of the show has turned up online, despite being popular enough in Asian territories to last three seasons.
