I need to get the green potion from the doctor to give to the gardener. I still need a red coral and a goatfish. It says the red coral should arrive in the box, but I'm 20% through and still have not received it... When should I be expecting it? In other posts people mention that they need the cowcod to get the potion, but on mine it is a goatfish. I have spearfished at the waterfall by the gardener at all hours and I can not catch this fish... Any suggestions?
