Plot
The episode begins with Garson Grunge, the garbage man, picking up garbage from the dumpster, thankful he doesn't have to work in the sewers anymore. Bebop and Rocksteady sneak into the nearby building housing Kraang's lab and acquire Mutagen, while complaining about having to run Stockman's errands. The Turtles arrive soon after, while being spotted by Grunge.

During the fight, Bebop throws the mutagen at Mikey's head. Mikey ducks and the mutagen breaks open in Grunge's face, sending him falling into the dumpster as he begins to mutate. Bebop and Rocksteady escape with some chemicals. Grunge wakes up, finding himself completely mutated into a pile of garbage and holding the turtles responsible. Grunge's eyeball, named Joe, convinces him that he can put his new look to good use, convincing him to stop the Purple Dragons from mugging someone nearby. A witness panics upon seeing him but the victim calms her down by telling her that he saved him. Joan Grody, who was reporting about the invasion, overhears and runs the new story, calling New York's newest hero Muckman.

The turtles catch the story and believe that Muckman may be up to no good, despite April's suggestion that he's called a hero. They all agree that they need to find him before Shredder does. The turtles ambush Muckman, who retaliates with a garbage tornado and sludge puke, knocking them down before fleeing from reporters and fans. April warns the turtles to leave and Mikey throws down a smoke bomb--but not before Joan catches a silhouette of the Turtles and airs it on television. Splinter, furious that they managed to get caught, and breaking the ninjitsu rule, grounds his sons and forbids them from leaving the sewers again.

Bebop and Rocksteady complain about getting another grocery run when they catch Muckman on the news. Rocksteady suggests that they use him to get the next ingredient.

Donnie runs some tests on the mutated puke and realizes that it can effect their own mutations. After Splinter takes away more of Mikey's things, banning him from even watching TV, Leo suggests that it's time to prove to him that they can be ninjas by sneaking out of the lair. Although their plan initially fails when they reach the exit, April helps them escape by distracting Splinter while they leave.

Bebop and Rocksteady look for Muckman, who attacks them until they tell him that they are his side. Muckman is lead to believe that they were mutated by the turtles and agrees to help them get the chemical they need, thinking it's a cure. The turtles arrive and Muckman attacks them with Rocksteady and Bebop. Joe continues urging Muckman to do the right thing, the turtles agreeing with him. Bebop hits everyone with a flash bang grenade and Rocksteady throws Muckman into the Kraang lab.

Muckman finds the chemical and takes it before being hit by the Kraang security system, Rocksteady taking it from him as the turtles rush in. Muckman retaliates against Bebop and Rocksteady by puking on them, which in turn destroys the chemical. As Bebop and Rocksteady retreat, Joe urges Muckman to do what's right so he apologizes to the turtles for accusing them of any wrong doings. The gang spot Joan and her cameraman searching the warehouse and Muckman distracts her while the turtles escape.

Splinter is angry at the turtles for disobeying him and leaving the sewers. Leo shows him footage of a news bulletin where Muckman is debunking any rumors that they exist. Splinter still punishes them... including April, who tries to sneak away but fails.

Trivia

 * The title of the episode is a reference to the 1984 horror comedy film "The Toxic Avenger".
 * Muckman speaks with a Jersey accent and has a license plate from New Jersey in his body, as his concept art reveals he's from Camden, New Jersey. References to "The Toxic Avenger" as it takes place in New Jersey.
 * Muckman is similar to Toxie as they are both mutants and heroes to their respected homes.
 * This episode shares plot similarities to that of the 80's episode Muckman Messes Up:
 * In both episodes, Bebop and Rocksteady search for mutagen containing a specific ingredient at a lab. In the 80's cartoon, they search for X-7, a chemical that can undo the Turtles' mutation while in this episode they search for a chemical called Reagent-X for Shredder's Mind Control Serum.
 * The creation of Muckman has mutagen falling out of the lab and hitting a garbage man. Where as the duo throw out Mutagen in the 80's cartoon and it hits two garbagemen, this episode has Mikey dodging a thrown canister by Bebop which hits the garbage man who lands in a dumpster.
 * Muckman is the city's "Monster Hero" while in the original cartoon he calls himself and Joe Eyeball "Mutant Heroes".
 * Muckman's ooze weakens the Turtles in both episodes.
 * In both episodes, the Turtles are considered criminals by the media. Though April proves them innocent to Muckman and Joe Eyeball in the original cartoon, it is the end of this episode where the Turtles are proven fictional by Muckman himself.
 * Muckman blames the Turtles for his mutation and works with the Shredder, Bebop, and Rocksteady in the original cartoon and teams up with Bebop and Rocksteady in this episode.
 * Both versions have Muckman joining forces with the Turtles at the end.
 * Both involve Muckman turning against Bebop & Rocksteady and ultimately throwing slime at them.
 * In both episodes Muckman thinks the Turtles mutated Bebop and Rocksteady.
 * Stockmans's grocery list:
 * Reagent-X;
 * 10 gallons maple syrup;
 * 500 packets white sugar;
 * Milk.
