Balloon
Description
The Balloon is an enemy which only appears in Hardcore and Voidcore modes. It also appeared in the Halloween 2026 Live Events. It has a balloon tied to its back which makes it fly, making it immune to collision damage, as well as making it undetectable by some towers and units. The balloon on its back pops when the Balloon loses all of its Shield Health, making the enemy vulnerable to collisions and ground towers. Its speed is also reduced by diving its speed by 1.5.
The Balloon can be spawned by the Grave Digger in Hardcore mode. The Balloon can also be spawned from the Mystery upon its death in Hardcore mode.
Logbook Description
"It’s not entirely clear why they are tied to the balloon. Perhaps it was a cruel joke by the Mandrakes, but the Balloon is left stranded regardless. The Void army is organized for what its needs are and, as it turns out, the Balloons are incredibly useful in battle. At first the Void Caster simply stared at the hundreds bumping against one another in the Vault, but then praised the little bush Mandrakes for their ingenuity."
Appearance
The Balloon has grey with a purple torso and legs. On its arms and head, it has purple veins. It flies in the air thanks to a balloon that is strapped to its back with rope. Once it loses all of its Shield Health, the balloon pops and it will drop down to the ground.
The legacy Balloon has light red skin, a brown torso and legs, and is faceless. It has one red balloon tied to its back. When it loses its shield health, the balloon pops and the Balloon walks along the path like any other regular enemy.
Strategy
- Cheap towers with flying detection like the Engineer, Crook Boss, Operator, Golden Soldier or Ace Pilot can be used to take the Balloon down with relative ease. However, it is still recommended to continue investing in flying detection due to the denser quantities of Balloons that spawn later on.
- Once it loses its Shield Health, the Balloon can be dealt with extremely easily, as it no longer has the Flying attribute.
