Part of a series of Nintendo-themed sculptures meant to be recreated in a more realistic manner, which started with the Realistic Piranha Plant (seen here: http://www.newgrounds.com /portal/view/513884 , and ends with a Baby Metroid in formaldehyde, which will be available in a few months.

It is a blue shell, as seen (and feared/craved depending on your position) in Mario Kart. I used clay and acrylics and the final piece is slightly over an inch in size, not counting wingspan.

And just in case, from the Q/A:
Q: No photographs? What about a photo of a painting I did in real life?
A: A photograph of a sculpture, painting, or some other piece of art you have made are in fact exceptions to this rule. Feel free to submit scans and photographs of your art if it's not already in a digital format.
