Anz Bitegard

A mouthpiece and muzzle to put onto captured Anz. All types are available, from bird's beaks to long snouts to the more abstract Anz mouthshapes.
It contains Frale Crystals embedded in the inner layers of the cloth fabric, closest to the snout or beak. It keeps the Anz calm enough when there are Humane walking by outside, but more measures need to be done once entered into the room.
Some masks allow a tube to be fitted to the mouth, so the Anz can and everyone can be safe.
