In "Fourth Grade", they bully the boys, pushing them down in the school corridor. While the boys have been promoted to 4th grade, they are now in 5th grade and believe they still can continue to bully younger children. Although the three claim to be 5th graders in that episode, they are seen with the 6th graders in subsequent episodes.
In "About Last Night..." the three are seen firing fireworks on the streets, this was their last appearance as a group.
They enjoy acting tough and picking on children who are younger than them.
