Also, only about 20% of the puffer fish out there are super-deadly. The usual puffer fish you find here on the East Coast, the northern puffer, has never had a recorded death due to its consumption. So, if Han Gang were to get it or one of its essentially non-venomous brethren, wouldn't really matter. (I say essentially because I think eating an Atlantic northern puffer's innards will make you "not well", but it won't kill you like the Japanese variety.)
Now monkfish/angler fish? They are all ugly.
ETA: Huh, apparently you are more likely to get saxitoxin poisoning from an Atlantic northern puffer than tetrodotoxin poisoning. If they eat infected clams down in Florida, they can accumulate it.
