The rhino, named Moyo, doesn’t even have a horn yet but that didn't stop him from pushing head-first into a spool in his pen, and the whole interaction was caught on video.
Moyo, which is Swahili for “heart,” lived up to his name as he proved he had nothing but that. Moyo pushed the spool around his pen from the middle of the area to the outer rim and would not stop.
