Animal Forest e+
Boy's Day is an event that happens in the games Animal Forest and Animal Forest e+. During the celebration, Carp flags will appear around the town. The flags are considered as a symbol of strength and wealth in Japan. Later on in the series in Animal Crossing: City Folk, Carp Flags were given out to Japanese players.
Boy's Day happens on the 20th of April to 5th of May. During this time, Tom Nook will sell the Samurai Suit in his shop.
The Celebration's name was changed to Windsocks in this game, but Tom Nook still sells Samurai Suits.
