Five screens, four minions per screen. But only two of the minions on each screen are good. The other two have gone purple, and bad! The good ones have a fart gun, the bad ones change back into good ones as soon as they are shot!
Ask your class questions, or give them tasks, if they are correct they can hit the space bar, shoot the purple minions and turn them back into yellow. Once they have shot at all 10, purple minions, they have saved the day and won the game.
Don't forget to have your sound turned up, nice and high.
