Donatello
- Donatello: Leo, you're not gonna believe this. Okay, I made this solution from the sample of the purple ooze, right, to expedite analysis of the isotope, but, while I was waiting for it to catalyse, I started thinking. If the purple ooze can people into animals, perhaps, if properly re-engineered, watch this, watch this, it could turn us... into humans.
- [demonstrates by giving his turtle hand extra fingers]
- Donatello: If we could get our hands on more of this stuff, it could be life-changing!
- Leonardo: We don't need that kind of change.
- [fighting on a plane after losing to Bebop and Rocksteady]
- Michelangelo: You can't just push past me like that!
- Raphael: You were being a nitwit! You were going to let it get by you!
- Donatello: I had it right in my hand, you acted like I wasn't even there!
- Leonardo: It is not my job to make your presence known, okay! Get your head out of your shell and communicate!
- Raphael: Well, what do you expect? He's all logic, no skill!
- Michelangelo: [to Raph] Well, coming from the guy who's all instinct, no restraint...
- Leonardo: [to Mikey] What do YOU know about anything! You're all heart, and no brains!
- Donatello: [to Leo] How could you? You may know a lot about strategy, but you know nothing about feelings!
- Leonardo: ...Fair enough. Wanna know the one thing I am feeling? We may be brothers, but we are not a team.
- [first lines]
- Donatello: Fellas, it's go time.
- Leonardo: Turtle Formation in three, two, one!
- [the Turtles attempt a Turtle Formation on the Chrysler building, but dogpile]
- Leonardo: What happened to Turtle Formation?
- Michelangelo: Turtle Formation? I thought you said "Squirrel Formation."
- Raphael: Why would he say "Squirrel Forma..."
- [hits Michelangelo on the head]
- Raphael: What's "Squirrel Formation?"
