Hey look, tortoises are just like us! It turns out if cockblock them, they will be super pissed off and attempt to hunt you down to make you suffer the consequences. Unfortunately, being one of the slowest living things on earth really hurts them in that department.
Seriously, though, this guy is kind of a jerk. Just leave the poor animal alone and let him get some. No need to be all up in his business like that.
