Rathtars

Rathtars were dangerous carnivorous octopus-like creatures that shared common ancestry with the Sarlacc. They had rows of razor sharp teeth, many tentacles and rows of orange eyes on their backs. Unlike Sarlaccs, they could move at great speeds, curling their tentacles inward and rolling like a ball. Han Solo transported three Rathtars on his freighter, meaning to give them to a collector called King Prana. When Han Solo, Chewbacca and BB-8 were boarded and confronted by two gangs, Kanjiklub and the Guavian Death Gang, Finn accidentally released the rathtars and they devoured most of the two gangs. The rathtars almost killed Finn, but Rey closed a blast door on the tentacle holding Finn before it was too late, releasing him. Thus Rey, Finn, Han Solo, BB-8 and Chewbacca were able to escape in the Millennium Falcon; they powered up to hyperspace while a rathtar was attempting to eat the cockpit and they flew straight through it.
