It reacts with hectical ringing when whistling, hissing, clapping, blowing and touching against the sensitive swan's neck.
With the door closed the PlingDing reacts on whistling, hissing, clapping, blowing and touching the sensitive swan's neck by giving a loud "Pling" out of its interior.
With the door open it is frightened by its own reaction.
Giving the "Pling" it is spluttering hectically.
