Bubble Creeper

The concept of bubble creeper is micro-vibration. Each part that reacts even with the minimum rod action. The worm itself moves even if the lateral movement distance is shortened ... So to speak, I wanted to make a "worm that moves without moving". In addition, the water receivers attached to various parts of the water stream firmly bite the water and move, and the tense body emits minute vibrations. The larger the size, the more I like this micro-vibration and the more I bite.
