Bunny Day Egg Hunt
To receive egg furniture on Bunny Day you have to participate in the annual egg hunt. Grab your shovel and use it to dig up eggs whenever you see an "X" mark on the ground. Open your menu and select the eggs to crack them open. The eggs will contain either candy or Bunny Foil. Give the Bunny Foil to Zipper the bunny outside of Town Hall to trade them for a piece of egg furniture.
Time Travel
Bunny Day comes only once a year and there are only 30 eggs to dig up. By setting back the clock on your Nintendo Wii you can experience Bunny Day all over again. Open the configuration menu from the Wii home screen and set the date back to a day before Bunny Day to hunt for eggs again. To avoid negative consequences, always time travel using the Wii's internal clock, not the in-game clock in your bedroom.
Profiting from Bunny Day
Even if you are not into the egg furniture set, you can always sell the items to Tom Nook. Each item in the egg furniture set is worth 9,000 bells, so a full set will net you 108,000 bells. Since the egg furniture set is only available one day per year, you will also find other players online that are looking for egg furniture items and are willing to trade bells or rare items to receive them.
From Egg Day to Halloween
When collecting egg furniture on Egg Day you will end up with a large amount of candy as well. Save the candy for Halloween, where you can trade them with Jack the pumpkin for the spooky furniture set. Set the clock for October 31st and look for Jack somewhere in the town. You must give candy to Jack to receive a piece of spooky furniture, however the other villagers will demand candy as well.
