What is Animal Crossing island

If it's for gamecube, you connect your gameboy to the gamecube, stand by the dock, and this little green guy that talks like a pirate will come up and ask if you want to go on his boat. If you say yes, he'll let you on, and sing a weird song while he's rowing. He'll take you to this weird island. It had like three people on it (animals obviously) and you can change it's flag and name the island whatever you want. Then when your all done and you want to go back talk to him, say you ant to go home, and he'll take you back, finishing the end of his song. Hope I helped!!
