Nintendo has announced two new DLC items heading to Animal Crossing: New Leaf players in North America (Europe unconfirmed at this time) during June and July.
The Rainbow Screen is the first DLC item that players in North America will experience as it will be available for download during the month of June. It resembles 2 clouds with a nice rainbow going across between them.
The Palm Tree Lamp will be available for download during the month of July. It functions as a nice lamp with a tropical palm tree theme.
Both of these items can be downloaded through SpotPass at the in-game Post Office on Main Street. Just speak to Pelly or Phyllis to receive your free item gift!
