Not usually? They have been and sometimes still are used as human food. I've touched some in the wild and they're just gross and slimy but not really that dangerous, but then I wasn't trying to eat it. Normally they just vomit their guts out to confuse predators, but some are poisonous to other creatures in the ocean.Sea cucumbers are usually poisonous, aren't they? It might actually be Water/Poison. :s
I'm surprised not many people are mentioning the Fighting typing for Nomakobushi.
I mean the Japanese word for "Fist" is in it's name and the description says it forms a fist from it's insides.
Sounds like a no brainer for it to be part Fighting type.
Seems like it was right in front of our eyes all along..
Spoiler:
This was so clever haha. It makes me wonder what else is being hidden in plain sight?
