Well, once again correct this injustice to those asked the question)

In General, in the achievements there is one where it is necessary to feed the rabbit-robot 3 carrots, I saw it when has passed. But the trick is that I feed him 5-6 pieces, and the achievement unlocked. What am I doing wrong? Thank you!
