The Sidekick is episode 1 of Season 1 of Sonic Boom, the CGI comedy series made by OuiDo! Productions with Sega of America. It premiered in the United States on 8 November 2014 on Cartoon Network, alongside episode 2.
Synopsis

Every hero needs a sidekick, and in the very first episode Sonic decides his is in too much danger. Eggman’s Burnbot sends Tails and his plane crashing to earth, and once his pal is bandaged up, Sonic lets him go, for his own protection.
The search for a replacement is a comedy of bad candidates. Amy juggles, Fastidious Beaver admits to cowardice, Knuckles thinks he is the one hiring, and the most promising applicant of all is Tails in a hood. Eggman applies too. Against his better judgement Sonic waves three finalists through, his old sidekick and his worst enemy among them, and sets them a hoverboard race to a flag on Mount Safety.
The doctor, of course, only wants both heroes out of the way, and Burnbot is waiting. On a frozen lake we learn the fastest thing alive can’t swim, and it is Tails who drags Sonic out of the water and flies them to safety. At sunset Sonic hands his best friend his job back, while at the shack Amy talks her way into a try-out as Knuckles’ sidekick.
