This ad is basically the same ad as before, except the only difference is the prizes. When you get inside the school, click on the guy. You will be brought to a mini-game. The objective of the game is to outrun the principal.
When you complete the mini-game, you will get two prizes, a Slime Gun and a Tricky Chicken.
If you are having trouble with the mini-game, below is a video tutorial of it!
Until next post everybody.
