Cataloging the first episodes all the catch phrases from the original cartoon started
 

Like the usual. The first episode, "Cowabunga" was screamed. The first, "Turtle Power," "Turtles Fight with Honor," "Go Green Machine."

Shredder's infamous line, "Tonight I dine on Turtle soup" was stated at the end of the 5th episode when he was pointing the retromutagen gun at the turtles before Splinter threw his cane and destroyed it.
