Pufferfish

Pufferfish are an upcoming item in Minecraft 1.7. This item was first introduced in snapshot 13w36a. The fish is large and yellow in appearance. Pufferfish can be caught by fishing and are in the good pile. Its main use is for potion brewing. Using a pufferfish in a potion gives the potion of Water Breathing, allowing for you to breathe underwater for 3 minutes. However, eating pufferfish is pretty much suicide. You will be given Hunger III for 15 seconds, which over time takes 3 hunger shanks, Nausea for 15 seconds, and Poison IV for a minute. Eating a pufferfish is the first and only way to get Nausea.
