MechaBot, a robot, befriends the school bullies, Bula and Billy. However, MechaBot's friends, Amato and Pian, discover that MechaBot has been sharing tips with the bullies, including advice on how to pick on Pian.
Later, while shopping at Mr. Gobi's store, they discover a mysterious device called the Ninjamera, which is used by a bad robot named Ninjamera. Ninjamera has been using the device to create infinite loops, trapping his victims and recording their embarrassing moments to upload online.
Amato, MechaBot, and their friends team up to track down Ninjamera and stop him. They analyze the locations of Ninjamera's attacks, which form a pattern resembling a duck's head. They predict Ninjamera's next target and set a trap for him.
Using a clever plan involving a mirror, they manage to reflect Ninjamera's loop attack back at him, trapping him in his own infinite loop. Ninjamera is captured, and the friends celebrate their victory.
The story also includes a subplot involving Deep, a friend who gets stuck in a comic book store and is rescued by the gang.
