Not to be confused with the 1987 TV series episode.

"The Big Blow-Out!" is the twentieth and final episode of the fifth and final season of the 2012 TV series, the one-hundred and twenty-fourth episode overall in the series and is also the series finale.

Production-wise, it is the fourteenth episode of Season 5 and the one-hundred and eighteenth episode overall. It first aired on November 12th, 2017.


The Turtles, their 1987 counterparts, April and the Mighty Mutanimals must work together to stop 80s' Shredder and Krang from destroying the world. Meanwhile, Bebop and Rocksteady are faced with a difficult and life-changing decision.

Shortly after the Technodrome powered up, the 12-Turtles, the 87-Turtles and April arrive at its old location. Although they do not find a trace of the Technodrome, but an ambush by some *foot robots on *combat machines. On screen, the friends are briefly taunted by the Shredder and Krang, before the robots go to attack and are processed by the Turtles team to scrap.

In the meantime, Bebop and Rocksteady are forced by their rolls donors to menial work and are constantly showered with insults. At the edge of frustration, they are sent by the villains to the old base of The Kraang, the TCRI building, to obtain some energy crystals. In the building, however, the two encounter some members of the Mutanimals - Slash, Leatherhead and Mondo Gecko - and the Earth Protection Force, who do their best to sully their business; but despite this intervention, Bebop and Rocksteady escape with the sought-after crystals. Mondo immediately informs 12-Michelangelo about the raid, but the Turtles arrive just in time to see Shredder help his two minions escape again.

With all the necessary components in their hands, Krang and Shredder raise the Technodrome to the surface where they are already expected by the Turtles, along with their heavily upgraded Shellraiser and Party Wagon. These bombard the mobile base, but the armor of the Technodrome easily withstands their new armament. The two villains now open their portal to Dimension X, to completely lay waste to the Earth with the help of Krang's Rock Soldiers; Traag and Granitor (or their 2012 versions) enter the city along with a great multitude of lower-level rock soldiers. With the Mutanimals and the EPF as support, the Turtles take up the fight against the stone invaders, forcing Krang and Shredder to intervene in the battle personally, and the tide begins to turn badly.

In the meantime, however, Bebop and Rocksteady are beginning to feel remorse: not only that Krang and the Shredder have lacked appreciation for them; but also that their maniacal plan to destroy the Earth, does not fit the two at all in the junk. Therefore, they turn against their two evil masters and cause damage to the portal projector, whereupon the rock soldiers are sucked back into their dimension by the closing opening. After Bebop and Rocksteady have done the Technodrome in, Krang and Shredder are taken into custody, the 87-Turtles say goodbye and return to their reality with their two prisoners, where they persuade their home versions of Bebop and Rocksteady to no longer be subordinate to ungrateful employers. And in the 2012 dimension, the local Bebop and Rocksteady decide to operate as superheroes from now on, and thus come to fame and honor.

The episode concludes with the music video, "Ice Cream Kitty".


  • This episode shares its name with the season 3 finale of the 1987 Teenage Mutant Ninja Turtle series.
  • This episode was released early on DVD in September 12, 2017.
  • An animated storyboard version of the final "Ice Cream Kitty Song" segment - composed and performed by Greg Cipes (Michelangelo) - premiered on October 7, 2016 at the New York Comic Con.
  • The image that comes to mind when Rocksteady mentions "Mother" is a representation of Russia's national personification called " Mother Russia ".
  • Krang was using “Chrome Dome Shampoo” which features a picture of that 80s character's face.
  • This is the last episode of the 2012 series in airing order.
  • When 80s Raphael speaks his first line in this episode, 80s Michelangelo's voice can be heard instead. This might be a reference to the occasional error in the 1987 series where the wrong voice comes out of the wrong turtle's mouth.
  • This episode marks the final appearances of Leonardo, Donatello, Raphael, Michelangelo, April O'Neil, Leatherhead, Slash, Mondo Gecko, Bebop, Rocksteady, the 80's Turtles, the 80's Shredder and the 80's Krang.
