- April O'Neil: Guys, we gotta do something. The Kraang are gonna poison the city's water supply with mutagen!
- Leonardo: The whole city will become a disaster area!
- Donatello: There would mutants everywhere!
- Michelangelo: Wow! Think of all the friends we'd make!
- [everyone stares at Mikey]
- Michelangelo: Excuse me for being a "glass-half-full" kind of guy!
- [last lines]
- [Donatello has built a laser-guided missile-launching staff... which starts to shake...]
- Donatello: It's not supposed to do that... RUUNNN!
- Donatello: Booyakasha!
- Michelangelo: Sounds weird when he says it.
- Raphael: It sounds weird when YOU say it.
- Donatello: [on zoom] Look at her, she's so beautiful. On this monitor she can't tell I'm staring.
- April O'Neil: You do know that's not muted right?
- Donatello: With all due respect Sensei, I can't keep fighting alien technology with a 6-foot staff. I was hoping to upgrade my weapon.
- Splinter: Hm... a 7-foot staff, interesting...
- Donatello: No, I meant using modern technology.
- Splinter: Ah, a solar-powered staff!
- Donatello: I'm serious, sensei.
- Splinter: I know. And yes, you may upgrade your weapon.
- Donatello: That's totally unfair! You can't just... did you just say yes?
