Seaweed-in-a-box

Seaweed in a box is made by adding ground seaweed to an empty box. In order to obtain an empty box, you must first talk to Harry in Catherby. To make the ground seaweed, the player must use Seaweed with a Pestle and mortar. Adding ground guam then turns it into fish food which can be fed to a player's pet fish. This is currently the only known way to obtain fish food, other than picking it up in Draynor Manor. Making it provides no experience in any skills and is only used to feed your fish and to be used in the quest Ernest the Chicken to poison piranhas and obtain the pressure gauge.
