"Journey to the center of the Gus" is the 74th episode of the series and the 11th(b) of Season 3 of Robotboy. In this episode, Bjorn Bjornson has created a nano killer-bot and had put inside of a soap that he will send to Tommy in order to destroy Robotboy. Luckily for Tommy, Gus eats the soap, and Robotboy has to save him from being exploded by the robot.
- The episode name is possibly a pun on "Journey to the Center of the Earth" by Jules Verne.
- When Gus eats the soap, Robotboy watches television. On the television appears Klaus Von Affenkugel in his mouse costume from the episode Wunderpark. In fact, the moving images on the television screen are from a scene from that same episode.
- Goof: When Robotboy scans Gus and his skeleton shows up, Gus is seen with a mouth full of teeth. His missing front tooth isn't missing but present. Before the skeleton check, Robotboy checked his internal organs and there the tooth was still missing.
