- Bait-and-Switch Time Skip: When Tails, Knuckles, Amy, and Sticks are under the effects of the evil cookies that Dr. Eggman created, Eggman puts them through villain school. We get glimpses of his lessons, skipping around from 1 to 4 to 7, etc. Then we get to lesson 12.Eggman: Lesson number 12, lesson numbering. Evil lessons should be numbered as follows: 1, 4, 7, 12, 16.
- Cutaway Gag: When Sonic notices the evil cookies Eggman left for him, he hopes it's better than the last time someone left baked goods on his doorstep.(cut to a flashback of Knuckles popping out of a cake, holding sparklers; he and Sonic stare at each other silently for several moments, Knuckles with a huge smile and Sonic with a bored expression)
Knuckles: Awkward?
Sonic: Awkward.
(beat)
Knuckles: It'll just be another minute.
(cut back to the present)
Sonic: (shudders) - Enemy Mine: When Sonic's friends compete against each other to try to capture Sonic, Sonic teams up with Dr. Eggman by feeding him a cookie with his DNA, turning Eggman into a fast, blue version of himself. Together, they take out the Badniks, and Eggman holds off Sonic's friends while he looks for DNA of his friends to turn them back to normal.
- Girls With Mustaches: Amy and Sticks acquire Eggman's mustache when they're under the effects of the evil cookies.
- Insane Troll Logic: Eggman has a basket of evil cookies dropped off on Sonic's porch for him to eat but he doesn't eat it, but when Amy walks by and sees the basket of cookies:Amy: Aw. I knew Sonic wouldn't forget my birthday. It's four months late, but it's the thought that counts.
Eggman: (watching from his lab) Gah! Why would he leave your birthday present on his porch? Where's the logic there? - LEGO Genetics: The plot device of the episode is a machine that takes genetic material to lace into cookies, which splice the traits of the sample into whoever eats them. Using this, Eggman plans to convert Team Sonic into evil, mustachioed geniuses like him. At one point, Eggman eats a Sonic cookie, and becomes a super speedy blue do-gooder willing to help Sonic undo what he's done.
- Mundane Made Awesome: This episode spends the first 2 minutes building up an unstoppable, almighty invention by Eggman that'll apparently defeat Sonic once and for all. Dark machinery is busy at work, dramatic music swells to a crescendo... cut to the ding of an oven timer as he's baking evil cookies.
- Overly Long Gag: Sonic finds cookies outside his hut, saying that he hopes it turns out better than the last time he found baked goods on his doorstep. Cut to Knuckles Jumping Out of a Cake, with the camera left running.Knuckles: Awkward?
Sonic: Awkward. - Victory Is Boring: At the end of the episode, Sonic feeds Eggman (who is under the effect of a cookie with Sonic's DNA) an evil cookie to turn him back to his normal self.
- You Have GOT to Be Kidding Me!: Eggman's reaction when Tails stops Sonic from eating the last evil cookie and eats it for himself instead (because it resembles Tails' favorite kind, chocolate chunk).
