- Ass Pull: In the first episode of Sonic Mania Adventures, Sonic pulls a Chaos Emerald from out of nowhere despite losing them all after the final battle with Dr. Eggman and Heavy King in Egg Reverie Zone and the episode taking place right after his return from his Modern self's world.
- Author's Saving Throw: Amy Rose shows up in Episode 6, likely in response to disappointment that she didn't show up outside of as an "Amy Doll" enemy in Mania.
- Awesome Art: The series uses the same animation style as Mania's opening, and it is glorious.
- Fight Scene Failure: The otherwise-awesome animation of the the series dips in quality during fight scenes, where the animators rely on lots of still-frames and have very little actual movement in stark contrast to how the characters are portrayed in every other scene.
- Fridge Horror: At the beginning of Episode 6, a Flicky becomes trapped in Metal Sonic's chest cavity when he lands on the poor bird, and is only freed when Amy helps Metal Sonic stand up. It's Played for Laughs (with the Flicky only being mildly dazed and punting Metal Sonic in the head after being freed), but it is shown that several months passed between the end of Episode 5 and when Amy discovers Metal Sonic, and the Flicky managed to survive presumably with very little food or water to go by. An illustration by Tyson Hesse perfectly illustrates the Flicky's supposed plight.
- Heartwarming Moments: In the Christmas special, Amy Rose goes out of her way to help Metal Sonic, despite quite clearly and understandably being afraid of him if her reactions are anything to go by. Regardless, she proceeds to take him back to Doctor Eggman, despite the fact they are both enemies of her and Sonic. Bonus points for Eggman taking Metal Sonic back after originally just leaving him out to rust, though that's slightly downplayed by the fact he ends up using Metal as a foot rest.
- Hilarious in Hindsight: A Running Gag in the flash animation Sonic Oddshow Mania is Spikes of Doom springing below characters from out of nowhere. This was also a subject in the first episode of Sonic Mania Adventures, released a couple of days later.
- Jerkass Woobie: Metal Sonic, in Episode 6, due to the fact he's depressed to the point he spends months laying on the ground because his failure affected him that badly, making him surprisingly pitiable.
- Memetic Mutation:
- From the first episode of Sonic Mania Adventures, people are already making reaction videos of the scene where Sonic is about to help Eggman, but changes his mind when he picks up a terminal he dropped. Like the above "Sonic gazing at a distance" meme, this one is exploitable too.
- In the fifth episode of Adventures, there is a shot of Tails choking on his chili dog◊ at the last second. Fans were quick to photoshop the image or Tails' face onto other things or make "Tails is dead" jokes.
- The shorts itself even fall into Fountain of Memes territory, thanks to a good numbers of wacky expressions and hilarious moments.
- Nightmare Fuel: Sonic Mania Adventures has more than a few comedic moments, but Metal Sonic proves to be a Knight of Cerebus in comparison to most of Eggman's robots, attacking Ray for intruding on the base's perimeter, and then holding him hostage by the throat to coax Mighty into giving him the Chaos Emerald he's holding.
- Tear Jerker: Episode 6. Metal Sonic, after the Anti-Climax that was episode 5, is left alone by Eggman and left in disrepair for months. When Amy finds him, the robot acts like he's depressed. It's disheartening to see the big threat end up so pitiful.
- Unexpected Character: As if Mighty and Ray's appearance in Sonic Mania Plus and the shorts wasn't enough, many people assumed Amy Rose simply wouldn't appear at all due to both her absence in Mania proper and the expectation that the five episodes that were made, where she was also absent, would be it. Yet they made the sixth episode where she become the main focus.
