Analysis, Discussion and Tips for Success
General Discussion
Giant frog spawn can be caught using a net at the same fishing spots where slimy eels and cave eels are baited. Their primary in-game use right now is as a secondary ingredient for making crafting potions.
Giant frog spawn are oddball items in that they are untradeable. This has significant implications not only for the profitability of this activity, but also practical considerations -- untradeable items cannot be noted, so if you fill your bank with hundreds of these, you're pretty much stuck with them. If you plan to make crafting potions that is obviously not a problem. Otherwise, they can be used as cheap food for activities where light healing is needed, or to top up health at a bank (they heal a random amount from 30 to 60 LP each). You can also feed them to cats.
About 10% of the time you will get swamp weed instead of frog spawn. These can be burned to soda ash and used to make glass, like regular seaweed (but be aware that the Superglass Make spell doesn't work with swamp weed.) Catching swamp weed only gives 1 XP though, for some reason.
Since frog spawn can be used as a secondary ingredient in Herblore, an expensive skill to train, I have assigned it a value of 300 gp. This is somewhat arbitrary, but I did want to give this item a value, so I chose something fairly conservative but still reasonable.
Location and Access
There are only a handful of places to catch these, and they are all in swampy areas. Low-level players will need to fish for them in the Lumbridge Swamp Caves. These are most easily accessed via the basement of Lumbridge Castle, which requires you to have at least started the quest The Lost Tribe. You also need a covered light source. To use this spot, bank at the Culinaromancer's chest in the basement, then go through the hole into the cave system. Run south and go through the entrance to the Lumbridge Swamp Caves. Run south and then east and you'll find a small body of water in the middle of the room with a fishing spot.
Once you are high enough level to use the fairy ring network, you should switch to the spot in the Dorgesh-Kaan South Dungeon, as it is a bit closer to the bank (in Zanaris). Just go to fairy ring code "AJQ" and run a bit northeast to the water where a fishing spot can be found.
Required and Recommended Equipment
You need a small fishing net and a covered light source. The best solution for those who have completed at least the easy tasks of the Seers' Village Achievement Diary, is to wear a Seers' headband (1, 2 or 3). Those with level 65 Firemaking can use a mining helmet the same way. When fishing in Dorgesh-Kaan, you need a lunar or dramen staff to access the fairy rings; this can be equipped.
Required and Recommended Supplies
No supplies needed.
Familiar Suggestions
Frog spawn is untradeable, which also means you cannot store them in a beast of burden. Thus, here you should use a fishing familiar, to increase fishing speed, and get valuable foraged fish.
Technique and Tips
Just follow the access directions above, fish until your inventory and beast of burden are full, and then bank.
