Darkling Tentacle

The Darkling Tentacle is an Ing that is essentially a long tentacle. It sticks out of the wall and swings back and forth damaging you if they hit you. They can be stunned with a shot from any one of your beams or can be rolled under in the morph ball. According to the logbook, there is no way to kill them; however, there is a way to actually kill them, which may be a log book error or a glitch, but a charged Light Beam or Annihilator Beam can destroy these creatures, but the success chance is about 20% with the light beam and 5% with the annihilator beam. However...Using the Dark Beam against it would not mean that the Darkling Tentacle would be hurt or killed
