Crash Test Pony

I have been tasked with recreating a life-sized version of the Canterlogic Crash Test Pony from My Little Pony: A New Generation. I need just a simple, unrigged, untextured model. While the surfaces should be smooth, the model surfaces should need the absolute minimum level of detail. The surface geometry itself must be kept relatively simple, with few holes and intersections, so I can modify it easily for 3D printing and to add features to the internal structure. These will include things like attachment points for an internal PVC pipe skeleton, places to attach lights and/or laser diodes to the eye sockets, and other internal structure pieces that shouldn't affect the surface. There are relatively few images of this character. The attached image is all available concept art and screens from the movie. There are some differences between the concept images and the movie screenshots. Please note that the tail is actually modeled in a very similar way to the legs in the movie, and not simply a tuft of hair as it is in the concept images.
