I couldn't tell you the most violent passages, but I do know they were a-plenty. I remember as a 10-year-old being incredibly underwhelmed watching the show, when you compare the level of gore from teeth, claws, and blades in the books, with the Disney-ized (or Nickelodeon-ized) violence in the show which usually involved Andalites arm-wrestling or a lion pushing someone into a pool of water.
