Hot Air

Balloon
Balloons are sentient inflatable balloon creatures.

Balloon creatures are very diverse and come in many shapes and sizes.

Known examples of balloon creatures:


 * Octopuses


 * Octoboss


 * Bugs


 * Worms


 * Dragon snakes


 * Squeak the Dog

Drivers
A few of them, mostly the hot air balloon variety, have a symbiotic relationship with a bean person riding a basket hanging from their strings below. The relationship is comparable to a human riding a horse, but seeing as a single balloon founded an entire Hot Air Balloon Travel Company at the end of Mega Mash, it is unclear whether the balloons and the bean people see treat each other equals or subordinates.

The role of the driver in the basket is most likely to operate the fan. The fans are not only used to help move the balloons much easier with the added weight of the driver in the basket but also to interact with certain objects from a distance that would be impossible for a balloon to do by itself. Not only do plenty of mechanisms in the World of Air require a fan to operate like blowing a pinwheel or putting fires out, but it's also useful for defense by blowing hazards away.
