A wild eastern box turtle with a fractured shell at a US zoo had trouble moving.

So with some creativity, ingenuity and sketches, a veterinary student designed and built a small wheelchair for the turtle. The material? Lego pieces.

The injured turtle was found by an employee of the Maryland Zoo in Baltimore in July. It was taken to the zoo's hospital, where veterinarians found several fractures on the bottom part of its shell.

The injuries were unusual for being under the shell, not on top, so the challenge became how to let the animal move around and also let the injury heal.
