Hmm... Fishing minigames? That reminds me of Oregon Trail II or III, can\'t remember which, but they had this kind of \'thing.\' However, I do have a few points to make.
One: Like SnowWolf said, there is an underwater race. Klyros can breathe underwater as well. And the bottom two levels of Yliakum (I never spell that right) is submerged in water, if I remember correctly. So, this leads to point 2...
Catching fish with your hands. If you can go underwater, then go, and catch some fish with your hands. However, as it is a city, there may be cattle-like farms underwater, except instead of cattle, there are fish. So to find fish that you can actualy \'get\' for free, this leads to point three...
Catching fish underwater, underground. This is, after all, a large cavern, so underground streamds, rivers, and perhaps oceans could be there, but the creatures are underwater as well, so they probably have night vision or no vision and a keen sense of smell. Anyway, what I\'m trying to say is...
Is that I like the idea of fishing, and am suggesting that you can catch fish with you rhands. Also, this is underground, so we\'ll have to make creatures the type who live underground and in water.
