Pufferfish (item)

Pufferfish is a highly poisonous food item and potion ingredient.

Fishing
The most common way of obtaining pufferfish is fishing. The wait time of one being caught is decreased with the Lure enchantment and the chance of one being caught is slightly decreased with the Luck of the Sea enchantment (named as such because it increases treasure, not fish).

Guardians and Elder Guardians
Guardians and elder guardians drop a random fish as a rare drop besides the common raw fish drop. This has a 13% chance of being pufferfish. The chance of getting a fish can be increased with looting, but the type of fish is not affected.

Fish
Pufferfish mobs 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.

Ocelots
Pufferfish can be used to tame ocelots, get cats off of chests, beds, etc., breed cats, and make baby cats grow up faster by 10% of the remaining time.

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. 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.
 * If this dish is prepared incorrectly, it can be lethal through respiratory paralysis. Therefore, any chef preparing fugu would have to have special licensing/certification to prepare this dish.
