Howlers were a quadruped creatures that when frightened would emitt a sonic noise that would deafen and scare off any predators. They had a long reptilian neck and were agile like lizards. They could be found on Yavin IV in and around the Massassi Temples. Jaden Korr and Rosh Penin had to fight off some howlers when they were making their way to the Temple after their transport had crashed and they were separated from the main group. Jaden later encountered two hiding away in a crevasse in the training arena where he had to leap across the bridge.
