Fishbowl helmet

The Fishbowl helmet, often called a space helmet, is obtained from Murphy in exchange for a fishbowl during the Freeing Pirate Pete subquest of the Recipe For Disaster quest. It is used, along with the Diving apparatus, to dive underwater. The Fishbowl helmet can be obtained from Murphy for free after Freeing Pirate Pete without the exchange of a fishbowl.

In The Great Brain Robbery, this helmet is used with the Diving apparatus, to dive in the underwater tunnel on Harmony Island.

If you lose the Fishbowl helmet, Murphy will give you a new one if you choose the diving option when talking to him. This helmet cannot be stored in the Costume room of a Player-owned house.

Trivia

 * There is a glitch where when mining, the player's head will sometimes "leave" the fishbowl.
 * Wearing the Fishbowl helmet, together with the Diving apparatus, is the only known way players are able to dive underwater.
 * After the quest, players may wear it for the looks, as it is a unique type of helmet.
 * If players get a random event underwater, the random event will be wearing a Diving apparatus and a Fishbowl helmet, just like the player.
