These parasitic worms are introduced into the ear, back of the throat or under the chin (possibly into the aorta ) via a puncture. They do not develop fully but grow to be big enough that, when subjected to a high pitch sound from a whistle, become very agitated and cause the host to freeze or in mid-stride, fall. Infected people standing, will freeze upon the high pitch whistle and, in such a catatonic state when given a suggestion to disperse will readily comply. Much more elaborate suggestions can be delivered, like "cluck like a chicken when you see a bus". A vey busy chicken you will become.
