We learn that to make the mutagen, need to mix nyotrinaline and Taxon-9.
When Rocksteady says "It's turtle-trashing time!", Bebop's mouth moves to it.
Krang: (about the mutagen mixture) Now, all it needs is a pinch of Nyotrinaline.
Shredder: Nyotrinaline? You never mentioned that!
Krang: I thought I'd save it for a surprise, to keep you on your toes.
Shredder: Krang, you are unspeakably cruel!
Krang: Thank you!
April: Those unknown mutants have broken into the Mallory chemical plant.
Donatello: What could they want there?
Raphael: Maybe Shredder's looking for a new metal polish for his face!
Leonardo: It's Rocksteady and Bebop!
Donatello: I wonder why the temper tantrum?
Raphael: Beats me. Maybe they passed a mirror and saw what they looked like!
Donatello: That's right, Tin Face, and now you're taking the fall!
(Looks at camera) Now where'd I learn to say stuff like that?
Leonardo: Hold on, fellas, we can't leave the frogs like that!
Donatello: Maybe you haven't been keeping up on current events, Leonardo; they aren't exactly on our side.
Leonardo: Even so, they are mutants, just like us!
Michaelangelo: (to the Punk Frogs) Hey, wait a sec, dudes! I almost forgot. (Picks up box of pizza)) This ought to tide you guys over before you get back to bug city.
Genghis: Pizza? Ugh! Thanks, but no thanks.
Rasputin: Yeah, we hate pizza.
Donatello: Do you believe it - they don't like pizza?
Michaelangelo: Yeah, some mutants are just plain weird, ya know.
Raphael: (To the Punk Frogs) Give up, you guys, or it'll be sautéed frog legs for everybody!
Shredder: (Introduces the Punk Frogs to Bebop and Rocksteady) As Splinter has done with the Turtles, I have named them after personal heroes of my own -- Atilla the Frog, Genghis Frog, Rasputin the Mad Frog, and Napoleon Bonafrog.

Origins of the Punk Frogs Names
The Punk Frogs all have names that are allusions to great historical figures:
Attila the Frog: Atilla the Hun, leader of a group of Indo-Europeans that sacked the Roman Empire in the fourth century C.E.
Genghis Frog: Genghis Khan, the ruler of the Mongol Empire that included almost 80% of Eurasia. The Russian Empire, Ming China, the Ottoman Empire, and the Mughal Empire were remnants of the Khan's regime.
Napoleon Bonafrog: Napoleon Bonaparte, emperor of France from 1800 to 1815. Bonaparte added the Benelux countries, the Confederation of the Rhine, most of Italy, and the Illyrian Provinces to the French Empire. He invaded Austria, Prussia, and Russia.
Rasputin the Mad Frog: Rasputin the Mad Monk, a controversial figure in the era of the collapse of the Romanov dynasty of Russia before the formation of the Union of Soviet Socialist Republics. Grigori Yefimovich Rasputin (his full name) was seen as a traitor to the czar's government, a charlatan that tried to dominate affairs, and was eventually assassinated.
