Synopsis

Tails’ latest invention needs work. Fired straight off the drawing board in mid-battle, the Unbolterizer misses its target and nearly buries Amy, Knuckles and Sticks. Their fury (Sticks decides he must be a mole) sends Tails off alone to fix it.
Moments later the others are nearly flattened by a road train. Its driver, the ringmaster T.W. Barker, is short of acts (food poisoning, he says), so Amy volunteers everyone, and a quick dare gets Sonic on board. Soon the whole team is in the ring, from human cannonball Knuckles to Amy, a deeply unhappy sad clown. The show is a smash.
Too much of a smash: Barker’s old troupe ran away, and he has no intention of losing his new stars, who end up behind bars, with Sonic sealed in a sphere bought from Eggman Industries. Luckily Tails, who has spent the day perfecting his invention by repeatedly zapping Eggman’s TV remote, comes looking for his friends, rips the tent off and blasts them free. Barker gets a spin in his own sphere, and the team owes Tails an apology.
