... the kid should love a Tofu Bear, right? It's made from SOYSILK¨∆, a registered trademark name for some kind of soybean byproduct that somehow gets spun into plush fabric. The bear is plain white, with absolutely no distinguishing features. Just like tofu.
Tofu Bear costs $39, a bit steep, but probably the best price you'll find for a soy-based plushtoy [tofubear.com. really. via treehugger]
