King Rus

Queen Barb felt ill with Tonsillitis, which results in her not being able to lead. To which she appoints Rus as a King of the Playground during her absence. Under Rus' tenure, he enjoys his role as the King although soon tyrannizes the playground as he becomes more forceful for the students and organizes time for students to meet him, including the gang, more so than Barb.

After solving a dispute between two first-grade girls, Rus starts acting more and more like Queen Barb, 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 Rus 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 abruptly cut as Barb has returned, presumably recovered, to regain her rightful place. Subsequently, she regains her royal powers from Rus, 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 Queen Barb asks Rigalli to be Lord Emperor of the West Playground, much to her exhilaration.
