12 : Mob And Reigen: A Giant Tsuchinoko Appears [BETTER]
Arataka sees there is a reward for a tsuchinoko and calls Mob. They head into the forest looking for one, but he finds matsutake mushrooms and decides to collect them. A large monster appears, and Mob defeats it, making it spew all the mushrooms it ate and shrink. Happy with the number of mushrooms collected, Arataka decides to leave, saying that the tsuchinoko doesn't exist, without realizing the defeated monster was one.
