Pufferfish

The Pufferfish is an edible brewing ingredient caught by fishing and is in the good pile.

Using a pufferfish in a potion gives a potion of Water Breathing, allowing the player to breathe underwater for 3 minutes. However, eating a pufferfish gives the player Hunger III for 15 seconds, which over time takes, Nausea for 15 seconds, and Poison IV for a minute.

Eating a pufferfish is the first and only way to get Nausea in survival mode.

Pufferfish can be used to tame ocelots.
