in NF you can find these frogs at 14732, 34356.
Just make it easier, they are directly north of the little village in snowdonia with all of the trainers and merchants in it. OR directly west from the only bridge BEHIND the mile gate along the river.
They usually drop some loot that sells pretty nicely but the eyes do not drop very fast at all. Were giving me 2+ mill. exp per kill for oranges at lvl 29. The are around at all times of the day and are weak to thrust weapons. Not sure about magic though. All and all a good hunting place from lvls 28-32 for the exp and loot.
