From the inside, the Ark does indeed resemble a barnlike floating refuge from the stormy seas of modern life, but the only animals aboard this Presidio Heights toy emporium are the wide array of kid-sized stuffed beasts ideal for cuddling. What's really being preserved here are Slinkys, Frisbees, jigsaw puzzles, boomerangs, hula hoops, building blocks, Whiffle balls, Radio Flyers, and other tactile, time-tested gadgets for the preteen set. Budding scientists will enjoy the butterfly gardens, ant farms, and home planetariums. Glitter, stencils, and crayons galore are provided for the artist-to-be, and a fine collection of toy trucks, train sets, and model airplanes is nestled among the spinning tops, bubble wands, popup books, pint-sized kitchenware, Matchbox cars, Mr. Potato Heads, and cowboy/pirate/knights of old action figures. If you're looking for a mind-numbing video game aglow with EMF emissions, you've come to the wrong toy store. (Other locations in Noe Valley and Berkeley.)
