Maria: What do you do if you come across Kappa, the river monster?

Qu: Is that the guy that catches those creepy fish?

Maria: THROW A CUCUMBER AT IT

Qu: ???

Maria: You don't know Kappa? I’m surprised, you know all the yokai. 

Qu: Not that one. Does that translate to river child?

Maria: That's the one! Kappa is the mythical frog/turtle/child creature that has webbed feet and hands, a turtle shell on its back, green and yellow scaly skin, and a hollow head that fills with water. 

Qu: What's the point of the bowl of water?

Maria: It holds all the creature’s supernatural powers. Obviously.

Qu: So, why do I have to throw a cucumber at it?

Maria: It only responds to politeness and cucumbers, so if you are ever face to face with one, you better bow like a sumo wrestler or have cucumbers prepared. 

Qu: What happens if I don't?

Maria: It will either drown you or eat your liver and then drown you. 

Qu: Sounds like a lot of yokai. No way out.

Maria: Unless, yet again, you have fruit and vegetables on hand.
