Michelangelo, Raphael and Leonardo watch eagerly as Donatello puts the finishing touches on a new device, which they believe to be a new microwave pizza oven. Instead, it turns out to be a time-stopping machine, and the disinterest of the other three Turtles irritates Donatello. Anything that the machine is focused on will be frozen in time.
Meanwhile, a mad scientist known as Professor Lloyd Cycloid floats through the sewers on a homemade raft. His goal: create a satellite that will turn the rest of the human race stupid, so he can dominate them with his intellect. While Donatello is having pizza with the others, Cycloid spots the Time-Stopper and steals it. The Turtles try to intercept him, but are zapped by the Time-Stopper.
April covers the theft of a solid gold Egyptian statue (later revealed to actually be iridium), and Splinter recognizes the effect of the Time Stopper. He is horrified to find the Turtles frozen in mid-air, but fortunately they snap back into normal time shortly thereafter.
Cycloid uses the Time-Stopper a second time, this time to steal a powerful laser gun. April recognizes him from the camera footage, and Donatello sets out on his Sewer Ski to find Cycloid and reclaim his invention, leaving a trail of arrows for the other Turtles to follow.
Cycloid and his stolen items arrive back at his long-abandoned home, shortly followed by Donatello. Donatello is hit by the Time-Stopper again. While he's frozen, Cycloid dangles him over a vast pool of toxic slime that will kill him if anyone opens the door. Despite his perilous situation, Donatello manages to sabotage Cycloid's laser device, causing it to blast out of the house.
The other Turtles follow Donatello's trail through the sewers, and burst into the room where Donatello is suspended. Just before Donatello can fall into the acidic slime, Leonardo uses the Time-Stopper to save his life and proceeds to hand Cycloid to the authorities.
The priceless Egyptian relic is returned to the museum (and presumably the laser ray is returned as well). The other Turtles are in favor of getting rid of the Time-Stopper, but Donatello is outraged by the idea. Raphael responds by deliberately dropping the Time-Stopper, destroying it, and a mournful Donatello laments that it might take years for him to fix it.
