Pretty funny Sonic parody.
I like how you referenced Sonic 1, Sonic 2, Sonic CD, Sonic 3 & Knuckles, the Sonic Adventure series, and Sonic Heroes in chronological order. I also like the fact that you pointed out the problem with the franchise: all of the sidekicks. I loved the running gag with Dr. Robotnik/Eggman having heart problems. Great job, guys!
