Having been fed up with not being able to keep up with Sonic for years, Dr. Eggman has no choice but to make his robots faster. The secret: chewing gum. However, not just any chewing gum. This kind of gum is speedmint gum. Whoever uses it will be fast enough to leave even Sonic in the dust. As Grounder tries out the speedmint gum, he goes too fast and crashes, losing the speedmint gum.
But it's not only Dr. Eggman who's fed up with Sonic's speed. Tails has always wanted to be as fast as Sonic, but no matter how hard he tries, he's never in time for the fun stuff. Suddenly, Tails' luck changes when he steps in the speedmint gum Grounder loses. When Tails tries it out, he crashes into Sonic, surprised to see just how fast Tails can really go. Tails thought all his practice has paid off, but he really doesn't know about the gum stuck to his shoe. He then tries testing out his speed by racing a train, but as he gets across the bridge, he gets his foot caught in the railroad tracks. Luckily for Tails, Sonic thinks quickly by building a bridge over him.
After escaping, Tails looks for anybody in trouble. He mistakes a parachutist jumping out of a plane for someone in trouble, but the parachutist merely tells Tails he was in a skydiving contest, and that Tails made him lose.
Meanwhile, as Sonic tries to keep up with Tails, he finds Scratch and Grounder looking for the speedmint gum, thus explaining how Tails became so fast in the first place. Scratch and Grounder find out Tails has the gum, and they follow him to a thug's bar. While Tails is looking for someone in trouble, Grounder disguises himself as a little girl and tricks a pedophile biker into thinking Tails stole his lollipop. Tails escapes from the pedophile biker, but with the shoe that had the speedmint gum off. The pedophile biker then gets brutal at the robots because Grounder is not a little girl. Sonic then explains to Tails about his speedmint gum incident, and Tails asks if he will ever be as fast as Sonic someday. Maybe he will and maybe he won't.
What about the speedmint gum? Just as Dr. Eggman finds it, it gets eaten by a turtle. That hare certainly won't want to race that turtle now!
This was truly an exciting AoStH episode. The tables are turned, as Tails becomes the fastest and Sonic has to keep up with him.
