Cool house ideas for Animal Crossing: Wild World?

Does anybody have any ideas for the DS VERSION of Animal Crossing??? For house???? I have 12 million Bells and I just can't seem to find a good house theme. I have the mansion and A LOT of money (Thank you, Action Replay! LOL, but the action replay was my friend's so I don't have it anymore). Any ideas will be helpful, provided that they are easy to get!
