There are several instances in the game where you will be thrust into a balancing minigame. The cursor will automatically move left, so you will want to use small taps to push it to the right and keep it in the middle. The balance meter will fill up quicker the closer to the middle you are. For this trophy, you must do all the balance minigames without failing once (reset the checkpoint if you do and you can try again). If successful, this will unlock after Spot's balancing minigame on the balloon in Chapter 3.
