Cragvision is a television found in The Land of the Cragnons. It was invented by the Cragnons and Cragnons watch many shows here (the shows are created with chalk and unlike all shows the show are only white-not even black and white.)
Cragvisions give out clues to Mario, Princess Peach, Bowser and the Pixls telling them what to do. For example the first Cragvision seen in the game has a man running around a Yoshi shaped statue. This was a clue telling the heroes to run around the statue.
Cragvisions are a portmanteau between Cragnons and Television. They are only found in the game Super Paper Mario and only three of them appear in the game.
