This one is based on dorkly's video of the same name.

So. It begins with sonic running in Green Hill Zone Until a Strange hedgehog Which looks like sonic in purple appears

???: Hey! Nice moves Sonic!

Sonic: Oh. Um. Thanks. Who are you?

???: It's me dillain the hedgehog! I'm a tottaly original character!

Sonic: Then why do you just look like a purple version of me?

Dillian: Duh. I'm a imperfect clone of you created by dr. Robotnik. The only difference between us is that I'm a respective member of Deviantart!

Sonic: Well that's fine.

Dillian: Also im pregnant with your child.

Sonic: What?

???: Actually it's my child.

Sonic: Who are you?

Sonia: Im Sonia the hedgehog. Im a genderswapped version of you from a another dimension.

Dillain: She accidentally got me pregnant when we were making out on a HUGE pile of chaos emeralds

Sonic: Why did you say that like it was a completely normal sentence?

And then Tailz flew down to sonic

Tailz: Yikes! What's wrong sonic!

Sonic: Tails! Thank god you're here! This whole level is being overun with creepy knockoff characters!

Tailz: Uh actually sonic im tails with a z. I have three tails and can inflate my entire body at will.
