...I seriously thought the Island was useless and never went there. I had to pay 1K Bells to go there (and I never had any Bells to spare, so it was a huuuge amount, lol) and there I could watch all the butterflies and fish, cause Kapp'n didn't allow me to take my equipment with me to the island...
I never knew the gyroid would lend you equipment, I didn't imagine I could talk to him, and I never tried to cause I have a natural aversion to gyroids XD
How wrong could I be? ^_^' Useless Island.
