i watched the animal crossing movie!

This is Gekijōban Dōbutsu no Mori. it is a 2006 Japanese animated film directed by Jōji Shimura and based on the Animal Crossing video game series. It was produced by Nintendo, OLM, Inc. and VAP and distributed by Toho. The film opened in theaters in Japan on December 16, 2006, where it went on to earn ¥1.7 billion (approximately $16,216,000) at the box office.
The film retains the theme of the video games, and centers on an 11-year-old girl named Ai who moves into a village populated with animals where she works to make new friends and find her own dreams. Gekijōban Dōbutsu no Mori was not released outside Japan, with Nintendo of America stating in 2007 that they had no plans for an English release. I watched a fan english dub on the Internet Archive. it is very good and you should watch it too! link is here. https://archive.org/details/animalcrossing-movie-eng-dub/animalcrossing-p1-eng.mp4
