The plot involves a girl named Ai moving into an Animal Crossing town named Animal Town. After meeting lots of people, working for Tom Nook, she soon makes friends named Margie and Rosie. She soon discovers a secret note-in-a-bottle saying: Plant a conifer on the snow festival and something miraculous will happen. After she receives many more letters like this, she plants what she's supposed to plant and on the Winter Festival. Soon, after that, her friend Margie, moves. She is then depressed and doesn't want to see K.K. Slider at the festival, which reminds her of the letters and Margie. That's when the alien falls and asks her to retrieve the broken pieces. She goes to a cave under the waterfall where she meets Margie again. They retrieve the piece hidden in the cave and goes back to the alien. But, the monkey had the exact same piece so the alien is confused. The piece Ai held was actually the alien that was coming in the Winter Festival. It then thanks Ai and goes home. The trees she planted was the shape of a star on that alien's ship. The Trailer can be found here: http://www.youtube.com/watch?v=OilVxAdN7sk
