I...don't know what to say about that... Fizz appears completely speechless. As for Chomper, I have no idea. He isn't sentient (unfortunately), just well-trained and expressive. He seems somewhat distressed...

Heya Fizz. You've been up here longer than I have so I feel like I should ask. How do you get people to stop trying to eat you?

- Nami.

Fizz:

Do you like my Electro Harpoons? They are really good for fishing.

- Rumble

People usually stop trying to eat me when they realize I have a trained shark... when I'm inland that doesn't work so well though. I usually poke them a couple times with my spear instead, it's very sharp.
I'd suggest trying to find a pointy weapon like a sword or dagger.


They seem to be. However, I don't understand how I could handle them underwater without shocking myself... there is a limit to what I'm willing to try. They also seem wasteful, as in you drop one and a lot of fish die electrified. While efficient it's not usually necessary.
I think I'd only use them if I need to kill a large amount of fish in a flash, maybe if I need to feed half of Bilgewater.
