Sonic the Hedgehog: Look at this, I took nine million steps today.
Dr. Ivo Robotnik: I was spitting out formulas, when you were spitting up formulas.
Tom Wachowski: I was breastfed, actually.
Dr. Ivo Robotnik: Nice, rub that in my orphan face. (00:30:15)
Dr. Ivo Robotnik: You know what's hard about being the smartest person in the world?
Agent Stone: Everyone else seems stupid.
Dr. Ivo Robotnik: Stupid, yes! Way to go! you got that one. (00:34:23)
Dr. Ivo Robotnik: I'm sorry, Mister...
Tom Wachowski: Wachowski. But everyone calls me Tom. Except my dentist, he calls me Tim. But it's gone on for so long that it would just be weird if I corrected him. (00:28:49)
Tom Wachowski: Why do you keep calling me Donut Lord?
Sonic: 'Cause you talk to donuts and then eat them if they get out of line.
Tom Wachowski: Again, fair. (00:26:27)
Dr. Ivo Robotnik: Eeny, meeny, miny... mayhem! (00:54:01)
Tom Wachowski: Hey. So, what's this next planet you're supposed to go to like?
Sonic: It's no Earth, I can tell you that. There's no people, just breathable air and giant mushrooms and stuff.
Tom Wachowski: Well, look at it this way. At least you won't be the only "fun-guy."
Sonic: No. Don't ever do that again! (00:49:46)
Answer: Robotnik is a genius inventor and the quill is an incredible source of energy, so presumably he will use it to power whatever invention he can create that will help him escape the Mushroom Planet and return to Earth.
Thank you.
