Rumble is the luckiest colt in the world, or at least he thinks so: not only does he get to hang out with his awesome older brother, Thunderlane, almost every day, he also gets to hang out with his idols: the Wonderbolts themselves! Given his connections to his brother Thunderlane, who is a newbie member in the Wonderbolts, Rumble managed to get a spot as a ‘Team Assistant’ with his recommendation, given Rumble is still too young to join the Wonderbolts Reserves yet.

The job is hard work, but means he gets to tour with the 'Bolts, hang out with them behind the scenes, and act as their gofer and towel boy, plus get a fair income. He even gets his own special 'STAFF' Wonderbolts uniform, unlimited access to the catering table, and to watch every show for free!

Also, it seems, the job qualifies him for some unwritten benefits which happen among the Wonderbolts after some of the practice sessions or shows; something which happens when their adrenaline gets them very worked up. Something that will change Rumble's life, in more ways than one.

The question he must ask himself is: can he bring himself to participate, or will he simply embarrass himself trying as he so fears he will?
