From Laughing Squid:
Dr. Carsten Plischke, a veterinarian in Enger, Germany used leftover bricks of his son's LEGO set to fashion a temporary "wheelchair" for a pet tortoise named Blade whose legs were weakened due to a growth disorder. The "wheelchair" was then placed onto Blade's belly to allow him to scoot around while giving the support he needs as his legs grow stronger.
