This is a Floating Gargleblatter. It ignites the gas within its cheeks and funnels the hot air into special sacks in its abdomen allowing it (and anything tied to it i.e a basket) to float up into the air. It uses its large ears to push itself forward and to steer when it needs to.
Also, if extra speed is needed (if the rider needs to get somewhere fast, or more commonly, if threatened by a predator) it raises its tail allowing the gas to be released...violently. Pushing it forward either gently or much in the manner of a deflating balloon (all depending on the panic and control of the gargleblatter).
a saddle was once used as the means of riding a gargleblatter, but the constant swaying and bobbing caused severe airsickness in a lot of the riders. Although, there are rumors of underground racing where young adolescents use specially made saddles to race the gargleblatters, an exhilarating yet extremely dangerous sport.
