If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Even the minions have to take care of their eyes. This minion will see a doctor today, so he can be sure that his vision is good and his eyes are perfectly healthy. The doctor will take care of his eyes using a few efficient tests and after that, the subject of these tests, the minion will be really happy because he will definitely see better. Play the game and hang out with him while the doctor is treating him and be sure that this way, his fright will disappear. Enjoy!
