I don`t suppose you know where I could source one of the electronic boxes with PA speaker and multiple choice sounds such as - donkey , cow , horse , siren , machine gun , etc
I have only ever seen one with machine gun RATATAT sound at a truckstop in southern germany, I did not have enough Deutchmarks on me at the time because I was in transit to the east and there was nowhere to change money .
I stopped on the return journey but they were sold out . bummer .
