The Animal Crossing movie (劇場版どうぶつの森) was released in 2007 and is based off of Wild World which was released 2 years prior.
This keychain is from the Mascot and Character Strap set, which features a small character figure, as well as a padded plastic strap featuring the same character.
The figure is still in its original packaging, though the plastic strap may have some dirt from age.
Have K.K. adorn your phone, bags, bracelets, whatever you choose, it'll be cute!
