A porcelain household closestool for pet
dogs with one trunk and two pieces of mint
foliages. Once the dog pees, the foliage will
give a gentle wave to it, as if it is saying HI,
while the host is also noticed to clean the
closestool. Both the foliages and dogs are
graceful ballet dancers.
The force driving the swing comes from the
device in the trunk. Actually it is a battery
which makes use of the urine to generate
electricity, so that the closestool doesnt
need any outer energy.
