A snake-like cryptid in Japan. The Tsuchinoko is known as a large and usually flat and very poisonous snake (although it prefers to flee rather than attack). It is said that it can make huge leaps followed by a second leap while still in the air and that it bites its tail forming a "wheel" to travel around.
Only fought on Nate's route. It can be found in Narumi Sewers after talking to the Adventurer. After beating him and obtaining the Dead Tsuchinoko, it can be traded with the Adventurer for an Item Breeder.
