What you are looking at is a lovingly-crafted Android robot plush bag created over the course of two weeks as a birthday gift. And you can totally rip this idea off.
"On and off it took about, I guess, two weeks? I needed to pick the materials, figure out the design and of course, a lot of sewing and testing. The hardest task was to come up with a design that makes it both a fully functioning plush and a fully functioning bag, while conforming to the mascot as closely as possible. The head was a big trouble also, being a hemisphere and thus required some mathematics to calculate the right size of each piece of felt. The internal space should just be enough to hold your D40 w/ lens should you wish. The external shell is very strong though so it certainly won't drop your camera."
