The turtles were on a building on the lookout for the Kraang at night. "Do you see anything, Donnie?" Asked Leo. "No, Not yet" Replied Donnie. Leonardo looked and saw the Kraang carrying mutagen to a building. "Hey guys! I see the Kraang!" Shouted Leo. Leonardo and his brothers went down the building with stealth while they were heading to where the Kraang were, they hid in the Shadows. They entered the building and saw a bunch of Kraang droids, so they stayed hidden. "We need a plan to-" Said Leo but he was interrupted by Raphael who said "or maybe this!" as he ran to the Kraang droids and bashed them with his sais. Leo sighed and the rest of the turtles joined in, "It is the ones known as The Turtles, Blast Them!" Said a Kraangdroid and the kraangdroids all blasted the ninja turtles.
But the Turtles managed to beat those Kraangdroids. They saw some more Kraangdroids that were pouring a mutagen canister in a very large canister and they were sending it on to a Kraang ship. Raph was about to strike but then he was kicked by some metal, the turtle turned around to see Dogpound and Fishface standing behind them. "Turtles!" Dogpound growled, "Ready to end this?" Fishface asked. "Yeah!" Rapheal said as he leaped and hit Fishface in the face. "Grrr!" Fishface growled and kicked Raphael in the front. Raphael leaped at Fishface again but this time, he knocked Fishface on the floor. Fishace got back up and tried to Stab Raphael with his knife, but missed, Raph used his sais to fight back and kicked Fishface across the room. Dogpound turned to Leonardo, Donatello and Michelangelo, He grabbed Mikey and Leo went after and Mikey and shouted to Donnie "Stop the kraang droids from putting the mutagen inside the ship". There was a ladder that got the kraang onto the roof, Donnie climbed and got on the roof, then he fought the Kraang droids.
Raph knocked Fishface into a wall, then Fishace tried to bite Raph but couldn't so he kicked Rapheal in the face 3 times, causing Raph to fall to the ground. Raph tried jump up but Fishface used his feet to pin Raph down then he grabbed Raph by the face and smashed him against a wall, knocking him out. Leo knocked Mikey out of Dogpound's grasp and Mikey helped fight Dogpound. Dogpound tried bashing the turtles but kept on missing, Mikey jumped at Dogpound but got knocked to the ground by Dogpound. Dogpound tried to bash Leo but missed, Leonardo climbed Dogpound's hand and slashed his face. Dogpund got up, angered and threw both turtles into a wall, not knocking them out but getting them stuck under chunks of the wall, Dogpound remembered where Donnie went and climbed the ladder. Fishface walked t where Leo and Mikey were stuck and kicked them, laughing.
Dogpound saw a few Kraangdroids destroyed and he saw Donnie fighting another one, he came behind Donnie and punched him. Donnie was confused until he saw Dogpound. Donnie only had a Bo Staff and thought that he would be useless in a battle against a mutant like Dogpound so he ran. Dogpound chased Donnie with the help of some foot bots until at one point Donnie was surrounded and the only thing behind him was big hole and if he went into there he would be mutated again because that's where the canister was being pulled up. Donnie saw there was a metal circle around the canister that he can walk around on, so he ran on the metal until he made to the other side. Dogpound walked on the metal then jumped over where the mutagen was and landed where Donnie was. As he was landing Dogpound accidently hit 2 chains that was holding the canister up to the Kraang, this caused the canister to tilt and some of the mutagen came out but no one was under where it fell so no one was affected, before it tilted Donnie and Dogpound jumped off it and went back onto the building. Meanwhile, back with the other turtles Fishface was still kicking the turtles and hurting them in other ways, but then Raphael woke up and punched Fishface from behind. Fishface fell and Raph got his brothers up from the ground by picking up the remains of the wall. The turtles grabbed a chunk of the wall together and threw it at Fishface, knocking him out.
Donatello continued to run but he found himself by the hole again. Seeing this, Dogpound tried push Donnie down the but Donnie held on to the canister hoping not to fall to his death Dogpound tried to jump at Donnie again and broke the other 2 chains holding the canister. Dogpound landed near Donnie when it happened, he held on Donnie, trying to kill Donnie, but Donnie touched Dogpound's head and stabbed the sharp point of his Bo Staff in Dogpound's belly, he heard Dogpound falling. Donnie had beat Dogpound but it wasn't over yet, he was about to fall in the smashed Canister beneath him, he closed his eyes as he hit the ooze
