Balloon

Balloons are entities which float upwards when placed.

Usage
When on a mob or a fence, balloons will attach to the mob or block, similarly to a lead. Balloons will float into the air faster than the speed the player flies up, but will be kept grounded if tied to a fence. If tied to a mob, the balloon will float away and carry the mob high into the air, before both eventually despawn.

When being shot by an arrow or a trident, it will pop, summon particles, and be destroyed. It drops nothing after being popped. You can smack the balloon in any direction (when tied to a fence post), and it won't burst. Instead, it will give way to the direction you are pushing it from and come back, like punching it.
