Production
According to Sam Freiberger, Sonic's complains at Meh Burger about the messages Eggman sent him was a joke that was added late in production. In the original draft for this episode, Eggman sent Sonic "An article about the Mayor not being born in Hedgehog Village" but the idea was rejected by the S&P.

Trivia

 * Nine days before this episode aired on Boomerang, Bill Freiberger released the title card for this episode on Twitter as a teaser.
 * The game that Dr. Eggman and his lackeys play at the beginning of the episode is based on Pong.
 * FriendSpace in this episode is a parody of Myspace.
 * SnarkChat in this episode is a parody of Snapchat.
 * Sonic saying "And the Blue Blur lines up for what is surely to be his 25th consecutive goal" while he is playing soccer might be a reference to the Sonic the Hedgehog series' 25th anniversary, which occurred a year before this episode aired. Given that Sonic Boom episodes are generally recorded over a year before they air, the recording of this episode would have taken place sometime around the 25th anniversary of the Sonic series, making this possible reference rather relevant.
 * Eggman pulling away the ball when Sonic is about to kick it, causing Sonic to trip and fall, is a reference to the football gag in the Peanuts comic strip where Lucy regularly pulls off a similar joke on Charlie Brown; Sonic even utters the common Peanuts catchphrase, "Good grief", after he falls.
 * Sonic mentioning Eggman sharing an article concerning Mayor Fink's poorly handled email server is a nod to a controversial event that Hillary Clinton was involved in.
 * In this episode, Eggman mentions the "Eggs Benedict", a meal he had Tails serve for him in "Can an Evil Genius Crash on Your Couch for a Few Days?"
 * Scrambler in this episode is a parody of Twitter.
 * Scrambler's name may be a reference to scrambled eggs (which fits with Dr. Eggman's egg-theme).
