Fishbowl

An empty fishbowl is an object created by blowing molten glass into the proper shape with a glassblowing pipe. It requires a Crafting level of 42 to make, and gives 42.5 Crafting experience when made. Once made, players can fill it up with water to get a fishbowl (water), use seaweed on the filled bowl to get a fishbowl (seaweed), and get Harry to put a tiny fish in it to get a pet fish. Doing this is a medium Seers' Village task. The bowl is also a drop from Mogres and Waterfiends.

It is also used in the Recipe for Disaster quest, in which players make it into a fishbowl helmet. This is worn in the helm slot and allows the player to go diving near Port Khazard or indeed anywhere (e.g. Dragontooth Island during Rocking Out).

It can also be won on the Squeal of Fortune during the Squeal of Neptune promotion.

An empty fishbowl is also the tertiary ingredient in infusing Karamthulhu overlord pouches.

Fishbowls are sometimes used to train Magic with the Lunar Spell Humidify, which fills any container in the player's inventory with water. Because the left-click option for a water filled fishbowl is to empty it, the spell can be cast at its maximum speed.

Players may receive fishbowls from opening a box of summoning ingredients, a possible reward from the Familiarisation Distraction and Diversion.
