The Fumo Fumo Plush Series, commonly referred to online as fumos and occasionally spelled fumofumo, is a line of plush dolls of characters from the Touhou Project universe, manufactured by the Japanese merchandise company Gift. Fumos are popular on the internet and receive much representation among the Touhou fandom. The design of fumos originated from a series of doujin works by the Japanese circle ANGELTYPE, depicting the character Sakuya Izayoi with doglike features and a chibi appearance. In 2008, Gift partnered with ANGELTYPE to produce plush dolls in a similar style.
