Rhythm is gonna get you tonight!
Each mini game gives you one task to do to the beat of a catchy tune. These tasks have different elements to make it more difficult. An example of this is boy in the park with his date trying to kick every ball that bounces towards him. What makes it challenging is the soccer ball, basketball and football bounce different ways and require different points to kick them properly.
The scoring can be brutal for some games to just get an OK to pass. You need to complete close to perfect in a game to get a Superb rating and a medal. Each medal will unlock more rhythm toys which are mini games and endless games. Sometimes there will be special unlock if you complete medaled game with a perfect score if you haven't already.
For those that are human, get stuck and don't complete the minimum OK at a game, there is the option that will allow you to pass the game and unlock the next game in the series. You have to go to the Cafe and speak to the barista. He will give you option of skipping to the next game. I needed it because I could not master that Monkey Clock to even get an OK. Damn monkeys but so cute.
