Flat Bonnie is called that because she’s, well, flat. And a bunny. She’s the lead character of a line of hand-made plushie animals, put together by a group of humans with a very specific agenda: Bringing attention to the number of real-live rabbits living in animal shelters and looking to be adopted by loving families. Flat Bonnie and Friends introduced several new designs at WonderCon this year, and you can see them (and more) at their web site, www.flatbonnie.com. Through the month of April, 10% of all sales will be donated to the Los Angeles Rabbit Foundation.
