If you wanna fly longer on these bad boys upgrade oxygen

They can inflate and then they can do three things, do a huge jump that will deflate them, float/glide, and do a knockback attack that is similar to the diplodocus' only attack. They can also seat more than one person at a time

Inhale to increase damage resistance, get a decent level saddle, back up slowly into turrets, tank all of the enemy's turrets

The gasbag should be in the multi-passenger section
