Plot
At the start, Tails is working on something in his workshop but then notices that all of his tools have gone missing. He calls for Sonic for help, and the dynamic duo head to Eggman's Lair, thinking that Eggman stole the tools. However, Eggman's tools are missing as well. Eggman asks Orbot and Cubot to search for the tools and capture the crooks who stole them.

While Sonic and Tails set traps for the culprits, Orbot and Cubot wander around a tree. Suddenly, the two robots are caught by a net. Then they look down and see, much to their surprise, a group of robots who look similar to Cubot! Orbot explains that all of the look-a-likes are prototypes of Cubot. One prototype, who wears a hat, tells that they were rejected by Eggman but then they escaped his lair. The two robots go and tell Sonic and Tails. After explaining the situation, one of the prototypes gives Tails his tools back. Cubot decides to stay with his duplicates, while Orbot goes back to the lair.

Inside the lair, Eggman asks where Cubot is, and Orbot tells him that he has decided to stay with the prototypes. Eggman is shocked by this and decides to get him back. Meanwhile, Cubot is seen on a chair answering the prototypes' questions. Eggman then shows up with his badniks and Cubot tells everyone to run away, but everyone doesn't budge, much to his chagrin. Luckily, Sonic and Tails know what to do, as they attack the badniks and save the prototypes. Cubot apologizes that he stayed with his duplicates and tries to give Eggman a hug, but he accidentally makes Burnbot malfunction, and Sonic easily takes care of him. The Eggmobile flies off, and Sonic promises the prototypes that he and Tails will take them to a safe place.

Back at the lair, Orbot and Cubot are seen doing chores, and Orbot welcomes his partner home.
