one of his MANY money making endeavors is to catch, boil, clean and then sell Spiny urchins...
yes, he really has sold some of them and I think his sales will pick up when everyone goes home for Christmas and will need to bring island gifts- these are nasty little fellows when they are alive though- they are appropriately named and actually try to poke you (at least I believe that the one I was playing with a while ago really did try to poke me with his HUGE needle spine) and when they poke you they put some kind of pain inducing poison in you...needless to say this is dangerous work!
