Koopasonic Rock TV

The Koopasonic Rock TV (or, just Rock TV) is a kind of television set seen in the Super Mario World episode, "Rock TV". The name Koopasonic is a parody of the Panasonic brand.

During the episode, Bowser invents a television for Dinosaur World that is made out of rock, yet is still able to receive broadcasts. Posing in costume as spokesman Robby Rockwell, Bowser is able to sell Rock TVs the the Cave People, as well as Mario and Luigi, who all purchase Rock TVs and watch them. An episode that everyone watches is Koopa Sez, however, Mario and Luigi's Rock TV breaks and they toss it out their window into the water.

However, the Cave People keep watching. Inside the televisions, it is revealed there are Koopa Wizards who proceed to cast spells on the Cave People so they get hypnotized and follow everything Bowser tells them to do. Bowser then tells them to get Mario and Luigi and bring them to him. At the episode's end, Yoshi starts eating the Rock TVs and then spits out Magikoopas that were inside of them.
