First of all, it's Fgro, not Fargo. It's intended to be a typo.

Second of all, why can't you read what they tell you, you ***?
You have to get a pearl from the ocean, (Search deep sea option in the boat) and then you
need the Frogga Hat(Search deep in the cave by the graveyard) Then click in the hat, in
your inventory, and choose wear. Now, go to th forest and there he is.

Why is this even a question? They bloody tell you exactly what to do, you just have to ask
the peasants and read...

sometimes it dosn't work the 1st time if your sim is low on focus or needs to sleep or eat
but apart from tht u mainly do wat the person above says wiv askin the ppl nd doing as it
says

I did the same thing. But i believe i may have messed it up. I know that frgo is in the
forest but my sim found him before she found the hat. And now its not an option to go back
into the forest and find him again with the hat on. I dont know what to do. Do i have to
start the whole quest over?!
