King Bob falls ill with Tonsilitis, which results in him not being able to lead. To which he appoints Gus as a substitute King of the Playground during his absence. Under Gus' tenure, he enjoys his role as the King although soon tyrannises the playground as he becomes more forceful for the students and organizes time for students to meet him, including the gang, more so than Bob.
After solving a dispute between two first-grade girls, Gus starts acting more and more like King Bob, even having his hot temper and bossiness. He even institutes a cookie tax and imprisons all students who refuse or are unable to pay it and anyone who criticizes or even tries to reason with him. Because of this, more and more students are imprisoned which they then realize that Gus has turned into a tyrant. The prisoners escape and decide to dethrone him although a battle ensures from the rebels against his guards. It is apruptly cut as Bob has returned, presumably recovered, to regain his rightful place. Subsequently, he regains his royal powers from Gus, leaving him to be a regular student again. The gang quickly forgive him despite his cruel orders to them included among the students of the playground. Then King Bob asks Spinelli to be "Lord Emperor" of the west playground, much to her exhilaration.
- Dialogue Error: Spinelli mentions becoming Lord Emperor of the West Playground. As she's female, the correct title would've been "Empress", though this could be a deliberate mistake.
- Dialouge/animation error: When Gus asks for apple juice, he's given orange juice instead.
- Animation error: Right after Gus becomes king and T.J. tells the gang they should congratulate him, his eye highlights are missing and Lily's shirt has yellow stripes
