What the Fluff? Festival
Sept. 26, Somerville

The Somerville concoction gets its due Saturday from 4 to 7 p.m. at Union Square, where Archibald Query's Fluff will be celebrated with a cooking contest (from Fluffernutter to Fluffachino), performances by The Flufferettes, and Fluff -inspired crafts and games. A marshmallow world indeed.
