Pufferfish (item)

A pufferfish is a poisonous type of fish that is used to brew water breathing potions.

Fishing
Pufferfish can be obtained through fishing. The pufferfish catch rate can be increased by Lure, which reduces wait time generally.

Pufferfish can only by caught when fishing outside jungle biomes and its variants.

Guardians and elder guardians
Guardians and elder guardians have a 2.5% chance of dropping a random fish upon death. This has a 13% chance of being pufferfish. The chance of getting a fish can be increased by 1% per level of looting, but the type of fish is not affected.

Fish
Pufferfish will always drop 1 pufferfish in its item form when killed.

Food
Pufferfish restores and 0.2 saturation, and inflicts  III for 15 seconds,  IV for 1 minute, and  II for 15 seconds. Unlike rotten flesh, it is not helpful to eat pufferfish while starving because they inflict more health damage than they earn.

Cats
Pufferfish can be used to tame ocelots, get cats off of chests, beds, etc., breed cats, make baby cats grow up faster by 10% of the remaining time and gain an ocelot's trust.

Trading
Master-level fisherman villagers buy one or four pufferfish for an emerald.

Trivia

 * The consumption of pufferfish inflicting the player with nausea and poison is actually based on reality, as real pufferfish contain the extremely dangerous toxin Tetrodotoxin within their organs, especially their liver. Tetrodotoxin leads to quick death through respiratory paralysis. Muscle tissue and blood only contain trace amounts. In East Asia, pufferfish are considered a delicacy known as fugu, as small parts of the fish are actually edible. Any chef preparing fugu would have to have special licensing/certification to prepare this dish.
