Balloon Block

s are a special block added on 6/12/2018 at 3:30 PM central time. They were on sale for a limited time, but are now available in some chests and in the shop. They are inflated by clicking on them, or by using a Lever, or Button. s can also be popped by clicking on them when inflated, but can be reactivated after being popped.

When the player clicks a, it inflates and appears any color. This was added due to the game having 1 million favorites. The base of the balloon is a small block about 1/3 of the height of the posts and is white colored.

They can also be merged together, which causes the balloons to appear larger, have higher durability, last longer, and lift more Blocks. If the player bought s before 6/21/2018, they were transferred into Star Balloons.

Trivia

 * A list of how many balloons it will take to successfully lift a block upwards can be found at Block Weight.
 * Players can merge the base block to any size, increasing the balloon's size the larger it is. This also applies to the Star Balloon Blocks.
 * Unmerged s will always provide the same amount of lift to a block. If the s are merged, then the lift starts off lower than the unmerged balloons, but will very quickly become more powerful after several s are merged. The relationship appears to be parabolic as shown in the image below. This odd relationship makes it very difficult to predict the number of s required to effectively lift a block.
 * Balloons can have blocks placed inside them, causing strange effects like the balloon having weight, but still putting negative weight on blocks, and the block itself causing the balloon to spin.
 * When activated they exert a larger Area of Influence then they actually take up for the 
 * Although s do not have the standard 1x1x1 dimensions of a block, they can still be scaled. Scaling a balloon is similar to multiblocking, as the balloon will simply become larger and stronger.
 * s used to pop after being inflated for a period of time.
 * 5 s can be obtained using the code "Happy Valentine's day".
