Not only the basic movements during water surface shaking and mid-straw rolling, but also the natural movements transmitted from the bottom to the tail at the moment of bottom touch or in deep areas where water pressure is applied.

Materials and shapes derived from a huge number of sample-ups and repeated field tests up to the coefficient of restitution of the material against water pressure.
Reproduce the feeling of life under all circumstances and let the bus use its mouth without giving a sense of discomfort.
