Balloons spawn in a variety of colors and shapes, and they can be pushed around. Balloons have a small chance of distracting mobs (who will attack the balloons instead of the player). They will pop if attacked, or if a nearby balloon pops, setting off a chain reaction. Popping a balloon causes 5 damage. Like all Character-Specific Items, this item shows on the map when dropped.
In Don't Starve Together, Wes can craft Pile o' Balloons using 4 Water Balloons. The number of active balloons is capped to 100, and balloons last only 3 days. Wes must have at least 5 sanity to blow up a balloon. If the player is below 5 sanity the animation for activating the Pile o'balloons will play but no balloon will appear. If Pile o' Balloons is left on the ground for 3 days it will become 2 mosquito sacs.
