Act I - Nostalgic Reflection

(Sonic is running through South Island for the first time in years, he feels nostalgic. He remembers the luscious smell of Green Hill, the beautiful atmosphere of Bridge and the crazy tricks he did in Jungle.)

Sonic: Ah, nothing like a nostalgic trip down memory lane!

Screen Voice: You've been doing that all the time since 2010...

Sonic: What do you mean?

Screen Voice: Sonic Forces, Lego Dimensions, Sonic Frontiers, Sonic Generations, Sonic Lost World (maybe, because Windy Hill), Sonic Racing Games, Sonic Dash...

Sonic: OK...

Sonic: Well, at least SEGA never exploited it...

Screen Voice: Sonic Gems Collection, Sonic Mega Collection, Sonic R, Sonic Classic Collection, Sonic Origins, Sonic Generations, Sonic Mania, Sonic Forces, Sonic Superstars...

Sonic: Stop! OK, just stop.

Screen Voice: Alright, if your childhood gets milked some more, which it most likely will, don't come crying to me.

Sonic: Well, they never rush the programming of my games!

Screen Voice: Sonic Adventure DX, Sonic Adventure 2 Battle, Sonic 06, Sonic Colors Ultimate, Sonic Origins...

Sonic: SHUT. UP.

Screen Voice: OK, yeesh.

Sonic: Whoop!

(Sonic dodges an incoming buzzsaw)

Screen Voice: What was that?!

Sonic: Looks like we're approaching Scrap Brain.

Sonic (dodging many buzzsaws): Whoa! Woop, woop, woop. Whaa! Dodge, dodge, dodge. (jumps over a giant mechanical mouth) Jump! (he falls)

Sonic: Aaaaaaaah!

Screen Voice: Sonic!

Act II - Inside Scrap Brain

Sonic: (hits the ground) Ugh!

Sonic: Ow...what the? This...this isn't Scrap Brain.

Portal 2 Announcer: Powerup initiated.

(Cuts to the giant mech that used to be Scrap Brain, uncurling itself from the sand, about a few seconds later, it cuts back to the inside. The inside is shaking and trembling.)

Sonic: Whoa, whoa, whoa! (falls towards and grabs on to a prism above a pit of spikes) Dah! (Sonic looks down) Ah! Oh, oh my gosh! Whoa! Oh shoot, I'm losing my grip. Yeah, I'm gonna die. Oh wait...(climbs up to the top of the prism) Whoa! Still gotta maintain my balance.

(Cuts to the robot, now almost fully stood up)

Sonic: Whaaa! Oh!

(Cuts to the robot, fully stood up, roaring)

Sonic: Gah! My ears! And the room's shaking more. Whoa, whoa, whoa. Whoa!

Portal 2 Announcer: Powerup complete.

Sonic: Phew! I didn't die, thank goodness.

(STOMP! STOMP!)

Sonic: Whoa, whoa!

Portal 2 Announcer: Warning: High Water Pressure. The area will fill up with water and will flood fully in 2 minutes.

Sonic: 2 MINUTES?! I GOTTA GO NOW!

Sonic (running): Huh, huh, huh, huh...

Sonic (jumping over pits of spikes, attacking enemies and boosting up the robot to get to the top of the area)

Sonic: Oh, that's a BIG jump.

(Double Jump, Air Dash, Air Boost)

Sonic: That was easy. (accidentally steps on a button)

Screen Voice: Anticlimactic...and convenient.

Portal 2 Announcer: Water pressure fixed. Draining the water.

Sonic: Wait, where is it gonna...

(Cuts to the robot's bottom between the legs, which spills water)

Sonic: You just HAD to show that.

Screen Voice: Tee hee. Just getting rid of curiosity.

Sonic: Yeah, but...that was so weird, it was best that you just didn't show that.

Screen Voice: Well, you shouldn't have questioned from where the water was going to leave.

Sonic: Touché.

Act III - Torso

(Sonic is now in the torso of the robot, instead of the bladder)

Sonic: OK, wow, that's a lot of slopes!

Sonic: Oh, they're far apart from each other. Slope parkour!

Sonic (spindashing up the slopes, landing on the next ones): Wee! Yay! Woo! Yahey!

Sonic: OK, one more slope to go. This is a tight jump, but I think I can make it.

Sonic (spindashing): Haaaaaa...(release)...yah! (looks down) Whoa...

Sonic (stomping): Hah!

Sonic: OK, now it's actual plat- that's a LOT OF GIMMICKS. Those see-saws from Starlight, the spike ball that sends you up from Water Palace, the rocket from Dead Line, the minecart from Underground that has a track that leads to a loop, that leads into moving platforms. And there are a ton of alternate routes, that have different gimmicks. The problem is the alternate routes are mixed up with the main one, so this is more of a maze.

(Sonic runs through the gimmicks, cuting to a different one after one is run through)

Act IV - DRaDOS vs. Eggman

Sonic: OK, I finally made it to the head.

DRaDOS: Hey, mortal being.

Sonic: Who are you?

DRaDOS: I am the brain of this mech, the head of all this platforming. You had your fun, but...I'm not gonna go easy on you this time. As soon as you step on the first platform, there will be a pit of spikes, and after you complete the first part, the spike pit will rise up, only getting faster and faster, as you progress through the parts.

DRaDOS: Trespassers like you are the reason why I decide to do this. Put them in danger, giving them what they want when they are in the torso, and then pit them into an even more dangerous situation.

Sonic: I can tell you were built by Eggman.

DRaDOS: Hohohohoho...that old fool? No, he's in my hands.

Eggman: Grah!

DRaDOS: Hahahahahahaha!

Eggman: Let me go, you nasty corrupt piece of tin foil!

DRaDOS: T...Tin foil?...

(DRaDOS launches Eggman towards the wall with his robot tentacle)

Eggman: Argh! Guh...nnnnguh!

DRaDOS (showing his glowing, blood red eye): Listen here...

Eggman: My eyes!

DRaDOS: I am not a piece of tin foil! I am made of the strongest titanium and lead the face of the Earth has ever seen. Of course (cuts to Eggman struggling), pathetic little humans like you wouldn't understand. Heh, then again...(cuts back to DRaDOS) I'm not surprised.

Eggman: I'll make you eat those words, you inorganic robotic freak. Just you wait.

DRaDOS: HAHAHAHAHAHAHA! What are you gonna do? (Mockingly) Are you gonna punch me? Cry for someone to save you?

(Angrily) Because this little blue NUISANCE can't save you. You're his mortal enemy. So, checkmate!

Eggman: I'm gonna blow. (presses button)

DRaDOS: Uh...nothing happened. Wow, how pathetic. Hahahahaha-(electrical fire)AAAAAAHHHH!

Eggman: Aha, I escaped! Sonic, take me to the top!

Sonic: OK, I guess...?

Act V - Escapism

(Sonic platforms through the head)

DRaDOS (burning and glitching): No-ot so fa-a-ast!

DRaDOS: Ne-ne-neurotoxin.

Portal 2 Announcer: Neurotoxin impossible, due to the overheating of the core.

DRaDOS: Shoot.

Sonic: OK, that was kind of embarrassing.

DRaDOS: Sh-shut u-u-up!

Sonic: No, it's my mouth, so I can do whatever I want with it.

DRaDOS: Ngaaah!

Sonic: I'm at the end, hah! Goodbye, tin foily.

DRaDOS (exploding): I a-am no-o-ot tin f-f-fo-oil!

(The robot is now destroyed)

Eggman: Hey, Sonic. Thanks for saving me.

Sonic: No problem.
