Balloon Pop is a game exclusive to the Fair. In it, the player will use their mouse to control a fan and blow around a small hot-air balloon with a puffle in it. They must bump the falling targets into the cacti on the sides, in order to burst the targets and get tickets. Occasionally, a small balloon will be released from the target. If the player runs into it, they will get an extra life.
The blue puffle is the default puffle to ride the balloon. If you are walking your own puffle when you enter the game, that puffle can ride the balloon instead.
