Squid

Squids were a type of underwater creatures and fully organic sea life.

Barraki Usage
After the Barraki were banished to the Pit and it was destroyed, they discovered the Squid. They could suck life energy from targets, and the Barraki discovered they make very useful and deadly weapons; and, henceforth, used them. The squids were specifically bred by Kalmah, and he is also the one who built the Barraki's launchers to help the squids travel quickly to their target. He would not allow anyone into the breeding grounds, ever since Mantax ate half the brood. Kalmah kept them half-starved so they would be eager and hungry for the next foe to drain the life energy from. The squid kill their opponents by attaching themselves to the target with their circular mouths, latching on with very sharp teeth and literally feeding on the life energy until the target has died.

If Kalmah were so to rub his tentacle across a squid, he would "hear" what that squid was willing to share, and get information from it.

Trivia

 * Squids were sold in boxes of 7, and came in shades of green and aqua. The yellow and orange ones were sold with the Barraki.
 * A squid was featured in the short Singing Squid movie.
