Several clothing items were changed between the Japanese and international releases of the game:

• The Three Arc Shirt (a.k.a. the Familiar Shirt) is replaced with the Fortune Shirt, due to the former's resemblance to Charlie Brown's shirt in the American comic strip Peanuts (which had ended its print run in 2000, shortly before the game's release).
• The Tomato Juice Shirt is replaced with the Fishbone Shirt, due to the former's design resembling bloodstains.
• The W Shirt is replaced with the Houndstooth Tee, due to the former's resemblance to the logo of American fast food chain McDonald's.
• The Puzzling Shirt is redesigned to use more pastel colors, also changing the bottom-center square from orange to purple, to reduce the design's similarity to the Rubik's Cube brand of toy puzzles.
• The I Love GC Shirt (itself a redesign of the I Love 64 shirt from Dōbutsu no Mori) is replaced with the Cherry Shirt, due to the former being a parody of the I ❤ NY logo, which is trademarked by the New York Department of Economic Development.

These redesigns are also carried over to Doubutsu no Mori e+.
