Teenage Mutant Ninja Turtles - Season 5 (1991)

Donatello has tricked out the Turtle Van, but while taking it for a test drive, it's stolen from him by a family of robbing hillbillies. Can Donatello get the Van back in time before his brothers find out?

An accident causes two garbagemen to mutate into Muckman and Joe Eyeball. Muckman's slime is found to weaken the Turtles, and Shredder tricks him into working with him.

When the city is hit with a sudden termite infestation, the only superhero who can help--Bugman--is too at peace with himself to aid the Turtles in defeating it

While testing an experimental Muta-Shooter invented by Krang, Shredder unexpectedly turns Napoleon Bonafrog into a muscular, monstrous version of himself.

A malfunction of Donatello's latest invention ultimately results in Raphael believing he is about to die, and ultimately trying to save the world by himself.

Baxter Stockman leads a swarm of flies in an attempt to conquer New York and prove his worth to Shredder and Krang so he can become human again.

Tired of fixing everything in the lair, Donatello decides to clone himself so he can work on his other inventions. However, Donatello's clone turns against him and joins the Rat King in an attempt to conquer the city with a rat infestation.

Bebop and Rocksteady botch another mutagen experiment, resulting in a giant ice creature who Bebop dubs "Frosty", and Shredder uses this monster to freeze New York solid, preoccupying the Turtles long enough for him to steal thermal explosives needed to melt the Technodrome free from the ice.

A nerd-turned-muscleman captures three of the Turtles, and a reluctant Leonardo must ask Casey Jones for help in rescuing them.

Using a hypnotic microphone and speaker, Shredder takes over a radio station and broadcasts a signal that sends the population of New York City sailing into a dimensional limbo dubbed "Krang's Chasm".

Raphael's latest study of disguises leads the Turtles to attempt a rescue when he is mistaken for a mobster named "Mad Dog McMutt".

Zach, the Turtles' young friend, is put into military camp by his parents after making numerous false reports of aliens, only to find two real aliens--Wingnut and Screwloose--brainwashing the cadets to be their army and must call in the Turtles to defeat them.

A mad professor named Mindbender creates a law-enforcement robot named "LEX" to clean up crime in New York, but LEX ultimately starts arresting numerous innocent people for the smallest infraction. With the other Turtles unreachable, Leonardo must discover his own innate skills to stop this rogue robot before he and Mindbender declare themselves dictators of the city.

Frip the Polarisoid arrives back on Earth with his family for a visit, and must ultimately ask the Turtles for help in reclaiming his camera while helping them stop Krang's latest plan to conquer the city

While on a visit to an Egyptian Exhibit, Michelangelo is mistaken for a Pharaoh named "Amun Turt-El", also known as "The Sacred Turtle".

The turtles, Groundchuck and Dirtbag are taken to Shellri-La by an alien "Turtleoid" named Kerma. Kerma seeks help from the turtles to defend his planet from a two-headed dragon named Herman the Horrible.

The turtles unmask the dragon as they prove that the menacing creature is actually operated by two renegade Turtleoid delegates. Kerma return the turtles back to Earth, where they destroy Shredder's new Technodrome Mark II and afterwards defeat Chrome Dome.
