The selang can use its Alien Piping. It then makes two Dagger or Poison Bolt attacks.

Alien Piping

The selang plays one of the following ear-bending melodies on alien pipes. One creature the selang can see within 60 feet of it is the only creature that can hear the melody. The target must succeed on a DC 14 Wisdom saving throw or be affected by the chosen melody.
