Frog spawn is a food item that heals 3-6 hitpoints when eaten. Eating it also yields the message: "You eat the frogspawn. Yuck." They can be used to feed a player's pet cat.
Members can catch frog spawn with a small fishing net in the Lumbridge Swamp Caves and in the Dorgesh-Kaan South Dungeon. This requires level 33 Fishing and gives 75 experience points when caught.
Members may also obtain frog spawn by catching a gourmet impling or looting a gourmet impling jar. This impling may be in the wild or in the Impetuous Impulses minigame.
