After speaking with Pikango and accepting the quest “Find the Fairy Fountain”, I was able to locate it. The problem is the cheeky bitch is asking for 100 Rupees to come out of her shell. Should I give her the money or is this a trick?
The great fairy fountain in Karariko village is likely the first fountain you will come across in Breath Of The Wild. It might seem a bit odd to those who haven’t played a Zelda game in a while, but this is fairly normal behavior for the fairy fountains. They want money and that’s it.
So to answer the question, yes, you should give a Rupees to the great fairy in Kakariko village, in fact, it will be well worth it in the long run as it will grant you spoke armor upgrades. It’s not a trick, so be sure to give her your hard earned money for your time. It feels like a rip-off, but it’s well worth it in the long run.
Once she has the money, you can take a picture of her to complete the quest.
