Giant frog legs are dropped by giant frogs in the Lumbridge Swamp Caves and by frogs in the jade vine maze. When eaten, they restore 200 life points. Giant frog legs are not sold by Hudo anymore, although he will offer to buy them for 1,000 coins each if you choose the option to "Talk-to Hudo". They can be used with a raw cave eel on the life altar in the Creature Creation to make a frogeel. They are a clue of where to find Solus in the quest Wanted!.
