The story begins with Sonic the Hedgehog, Amy Rose, Knuckles the Echidna, and Sticks the Badger having a nice, relaxing day at Sonic's Shack. Sonic and Amy are lounging on beach chairs, while Knuckles and Sticks are playing volleyball. Just then, Miles "Tails" Prower arrives with his "most brilliant invention yet," which he unveils to be a robot he calls "UT" (Universal Translator), capable of translating any language into their own. To demonstrate its capabilities to his friends, Tails activates UT and it translates the language of a bird in a nearby nest. Knuckles is impressed, until UT begins saying what he says as something completely different; Tails deduces that when UT receives speech that does not require translation, it will translate it into what the speaker really means instead, making UT a mind reader of sorts. UT then begins translating the subtexts of the group's conversations, such as Amy's disinterest in UT, Knuckles' low opinion about Sticks, and Sonic's notes about Knuckles' dimwittedness, which causes tension among them. Sticks, due to her paranoia, is violently hostile towards the invention. Amy then convinces Tails to shut down UT before it reveals anything "too sensitive" (just before it reveals from Amy's statement that she loves Sonic).
At Doctor Eggman's Lair, Doctor Eggman, Orbot, and Cubot are observing Team Sonic's conversation through Spy Bot. Noticing the friction UT is creating between the team members, Eggman gets an idea: if he replaces UT with a duplicate of his own, he could have it say whatever he wants with the intent to ruin their friendships with one another; once the group is divided, it would be easier for Eggman to eliminate them. Later that night, Tails is in his home, ready to sleep with UT nearby; he is saddened by his invention's poor reception, but is optimistic that UT will impress his friends tomorrow. As Tails falls asleep, Orbot and Cubot sneak into his house, steal UT, and replace it with Eggman's duplicate.
The next morning, Tails meets up with his friends at the beach again with the UT duplicate, hoping to get another chance; Sonic, however, quickly suggests for Tails to turn UT off. The robot then "translates" Sonic's comment into insults about Amy, then turns Knuckles' replies into insults at himself and Sticks, causing them all to argue. It turns out that the translations were coming from Eggman through a microphone at his lair. Alongside him are Orbot, Cubot, and the real UT, which translates his monologue into praise about the doctor; flattered, Eggman opts to listen to UT instead, and leaves his microphone. When examining the UT duplicate for flaws, Tails discovers it is a fake, exclaims this to his friends, and attempts to rally them for a rescue of the real UT. To his disappointment, the others do not follow, as they believe UT is more trouble than it is worth. Tails therefore leaves on his own.
Tails infiltrates Eggman's lair, passing its Motobug defenses, and intrudes on the doctor, still being flattered by UT's translations of his own speech. As Tails is cornered by Eggman's robots, he offers a deal with Eggman; if he lets UT go free, Tails will become the doctor's assistant. Seeing the benefits of having Tails' expertise, Eggman accepts the offer and has Orbot draw up a contract. When Eggman voices his concern that Sonic will definitely retaliate, Tails reassures the doctor by having UT record a message where he says he is staying with Eggman under his own free will. UT later returns to Sonic, Knuckles, Amy and Sticks where it delivers the message, shocking them all; UT then translates the subtext of Tails' message into a call for help, prompting Sonic and the others to save him.
While Tails and Eggman are working in the lair's lab, Sonic and the others attack the outer d
