By setting a mass burr on the tsuchinoko-shaped head, a "trembling" with a sense of life is produced. Even with no sinker or wacky, the movement and fall will be different by vertically or horizontally stabbing a flat body, so it is possible to switch on a bass under pressure by a large two-pattern approach. Tsuchinoko's head shape, inspired by black sea bream fishing, reduces the presence of hooks, which are uncomfortable.
