Windy Balloon

The Windy Balloon is a flying enemy which appears during Windy Day. While the enemy itself does not do damage, a Green, Blue, or Purple Slime will always be attached to it that will do damage, both while flying and after the balloon is popped. The balloon will pop if you hit it or get too close to the balloon.

Trivia

 * The Windy Balloon is the only entity classified as an "enemy" that otherwise deals absolutely no damage to the player.
