Wisp

Wisp is a ghost who will reward you for helping him on the Wii and Gamecube versions of Animal Crossing. He was absent from Wild World.

Finding Wisp
On Gamecube, he can be found in your town from 12AM to 4AM and you must help him by catching five spirits with your net for a reward. It can be hard to find all the spirits, which means that you must tape your eyes open or hold them open while holding on to the gamecube controller if you have been looking for at least two hours. (For your sake, just get the tape ahead of time) On City Folk, you can find his lamp somewhere in your town. It looks like a genie lamp. After 8PM, go to the bottom beach acres of your town and you will hear a voice. Follow the voice to find Wisp. He will either ask you to find his lamp, or if you already found it, he will tell you to go to your attic. When you go to your attic, you can rub the lamp and Wisp will give you a reward.

Wisp's Rewards
If you catch the spirits, or find his lamp, go to your attic and he will reward you with one of the following. He can get rid of all weeds in your town, Clear the cockroaches in you house (City Folk only) Paint your roof, (Gamecube only) Give you furniture, or give you clothes. Note: The furniture is not rare most of the time. It can be bought at Tom Nooks.
