You know that is Mrs. Halfcourt!

Those four were just random extras that don't speak for A.J. Howard to have rounded up to enhance the plot and not have to use voices having too many familar characters. I would have liked to seen the other two Punk Frogs come in as back up for Raphael and Donatello after their two friends/brothers wre captured with the two turtles, Mondo Gecko, and Tokka.
Slightly off topic but...anyone else get tired of Michelangelo and Leonardo always being the ones captured?
