Frog spawn

Frog spawn is a food item that heals a random number of hitpoints when eaten, anywhere between 3 and 6. Eating it also yields the message in the chat box: "You eat the frogspawn. Yuck."

They can be used to feed your pet cat and are only obtainable by fishing with a small fishing net in the Lumbridge Swamp Caves, requiring level 33 Fishing and giving 75 experience when caught.
