- "Hey, Let me play or I'll make up something to tell Miss Finster on you!"
- ―Randall in Wild Child
He has brown hair and slightly slanted eyes, like Spinelli. He is hunched, probably due to bad posture, or because he looks up to his parents and Miss Finster as his role model. He wears a violet T-Shirt, green trousers and green shoes.
Randall is the most unpopular kid in school for his snitch ways, resulting in him being banned from the Fifth and Sixth Graders' Club. He desperately wants to be accepted but won't stop snitching since he has a friendship with Ms. Finster. He also has a standard for snitching, as there are certain things he won't tell on you for. He sometimes can be an antagonist to the gang. For example, he took over the playground with Menlo in "Partners in Crime".
Randall and Finster have a special friendship. Randall's possible other friends are Barry and Scribe Kid as they, along with Menlo, were all on the same football team in Soccer Boy and were together at Menlo's Birthday Party in Some Friend. It is also hinted, in the episode "Randall's Friends", that he has a crush on Spinelli.
