Trivia

 * This episode written by David Wise mimmicks the plot from the The Transformers episode Kremzeek!
 * Going by official episode numbers, Donald J. Lofty has previously appeared in "Slash: The Evil Turtle from Dimension X", but this episode is actually his first chronological encounter with the Turtles, as he will claim in both that episode and his other appearance (in "Rebel Without a Fin") to have had previous dealings with them.
 * Raphael breaks the fourth wall by saying, 'This is gonna be one of those days'.
 * Donatello's "Automatic Pizza Dough Maker" is probably based on the 1989 toy, the Pizza Thrower.

Errors
Shredder's neck is coloured the same as his cape for the entire episode!

Krang's android body had finger nails just before Krang, Shredder and the mutants went of to investigate the Zipp's egg crash-landing on the asteroid.

One of the Zipps double after it eats a steel door handle and a parking meter despite the fact the creatures only double when they eat copper.

After the Zipp shrinks back to normal size it makes no effort to fly back onto the tower leaving Michelangelo to rescue him instead,

The strapping on Donatello's bo-staff is missing when he and the other Turtles look up at the giant Zipp eating the main tower of the candy factory.

Krang refers to the volcano the Technodrome is stuck on as a mountain even though he found out about the volcano in "The Dimension X Story"

As the Zipp eats part of Donatello's pizza machine, Donatello fully becomes Michelangelo.

Throughout the episode, the Zipp is either a darker or lighter shade of purple.

When the Zipp grows gigantic, it is indoors, but after the commercial, it's outdoors.

When the turtles are cleaning up, Leonardo is on the floor with Michelangelo and Donatello, then he takes Raphael's place, cleaning astop sign.
