The video above depicts Blade, a spur-thighed tortoise who was found to have a disorder that made him unable to move. Veterinarian Dr. Carsten Plischke built customized LEGO skates for the tortoise which allows him to move freely.
According to the video's description, The skates were built in a way "that could not only move about in a way that wasn't possible before, but that the terrapin can also slowly rebuild leg muscle as a result of the physical modification." Check out Blade roll freely in the video above.
