Rip lines are CGI graphic torn paper effect monsters similar to ghosts but they vibrate when a monster starts snarling. While vibrating, these monsters could scare a player during video games. These appear in many TV shows/Video Games/Movies including the higher rated movies such as PG, PG-13, R and A. For example, on Elmo Says BOO!, Frazzle's emotions on the song causes these to vibrate even though they are transition objects.
