Swallow Whole
Swallow Whole is the special of the Bunyip. It allows players to eat an uncooked fish (and gain the correct number of hitpoints corresponding to the fish you ate) if they have the cooking level to cook the fish.

Players can use raw fish on bunyip to get 1 water rune per hitpoint the raw fish would heal them by.

Raw sharks would provide 20 water runes, monkfish provide 16, swordfish provide 14, and so on and so forth.
