* If you ran out of lives during the boss fight against Execun in the True Ending route, you'll be treated to a most disturbing level in what is essentially a CallBack to Nightmare Beginning's worst ending but on a much frightening scale. To elaborate; it starts with a crying Cream witnessing her friends (including Robotnik) commit suicide one by one (in Sally's case, she allows a gigantic Chopper to bite her head off), then coming across multiple impaled heads of Tails Doll, and lastly... Seeing the sight of Vanilla, her mother hanged on a tree. Out of despair, Cream activates a speed Power-up to spindash her way through the spikes and kill herself.

** In the first segment that takes place inside Cream's house, if you get caught by an evil looking Vanilla you'll be treated to a jumpscare of her grabbing you.

* Tails and Cream's duo route has an unsettling ending. The two end up stuck in an elevator, and they have a heart to heart, going to sleep in a good mood... [[MoodWhiplash except when Tails wakes up, he learns, to his horror, that he has]] GoneMadFromTheIsolation and [[ImAHumanitarian begun to eat Cream]]. He tries to make the situation better for himself by turning the fact he was eating Cream into a FurryReminder (Tails is a fox, Cream is a rabbit), but [[SubvertedTrope that's not how Mobians work.]]

* Sally's route is made out of a copy of Freedom City, over which Exeller watches omniously.

** In the first one, if you get caught by an evil looking Vanilla you'll be treated to a jumpscare of her grabbing you.

** In Tails' route, if you jump in a tree (where Exeller is peeking) that is inches away from the green ring, a jumpscare will occur accompanied by a message that says "You found me. Good job."
** In the same route after Tails encounter corpses of the miniature animals, if you go back to the Tornado without grabbing a green ring Tails will briefly walk slowly before you gain control of him. Turns out Exeller is on the chase, and if he catches Tails, a jumpscare will happen.

* The Prison Tower Zone. Amy has to leave the prison complex to escape from Exebark and to re-unite with Cream. What makes it scary is that the stage is dimly lit, and worse of all, if you linger around without getting to a source of light, a 5 second timer will start and the ''Breathelessness'' theme will play and the stage gets darker as the timer counts down (which will accelerate it further if you touch an area filled with darkness). If the timer counts to 0, the screen will completely black out, and Amy gets killed off-screen.[[labelnote:*]]Amy's icon will have her eyes filled completely with blood.[[/labelnote]] Furthermore, the default continue screen which normally shows a character's soul will have a variation that reveals Amy's brutally mauled corpse with her soul standing over it.

** In Eggman's opening Zone, after Exeller has broken through his base. Eggman has 30 seconds to rendezvous with Scratch, Grounder, and Metal Sonic, if you run out of time, Exeller will be waiting at the end of the stage, pass through him and a jumpscare will initiate.
** In Eggman and Tails' route. If Eggman chooses to open the vents to clear out a fog, Exeller will enter through the vent and suddenly lunge at him accompanied by a jumpscare. After this, Exeller will take Eggman's place in the speaker and Tails will be killed offscreen.

* The Prison Tower Zone. Amy has to leave the prison complex to escape from Exebark and to re-unite with Cream. What makes it scary is that the stage is dimly lit, and worse of all, if you linger around without getting to a source of light, a 5 second timer will start and the ''Breathelessness'' theme will play and the stage gets darker as the timer counts down (which will accelerate it further if you touch an area filled with darkness).

** If the sole survivor decides not to obtain a black ring, Exeller will kill them before their respective final stage has started. If you wait at the character select screen that depicts a demonized Tails, Knuckles, and Eggman, a jumpscare will occur.

* The ''Exeller jumpscares'', especially since the game in general is seldom on this. The fact that it happens is a sign that you've screwed up pretty badly.

** In Eggman and Tails run. If Eggman decides to open the vents to clear out a fog, Exeller will enter through the vent and suddenly lunge at him accompanied by a jumpscare. After this, Exeller will take Eggman's place in the speaker and Tails will be killed offscreen.

** The occurrence in Tails' solo route is even ''worse'', as it has Tails walking through darkness, with images of Amy, Sally, Cream, Knuckles, Robotnik and Tails himself covered in blood [[MyFriendsAndZoidberg (and, for some reason, Alice)]] flashing before him. This signifies just how close Tails is to crossing the DespairEventHorizon.
