Irwin

Irwin is a third grader who made his debut in the episode "Home Sweet Home". He first met Buster at Camp Meadowcroak. Just like Buster, he is also a third grader.

When he first met Buster he asked him if he could use the lower level of the bunk bed since he has to go to the bathroom a lot and the bed was closer to the door, which gives the possible evidence he might suffer from Nocturnal enuresis similar to what Jenna has. He is very kind and he and Sanjeev both become friends with Buster.

He also stated to Buster that he had a snake named Busterfield that only ate crickets. He also has a best friend named Sanjeev who goes to the same school. He and Sanjeev have not reappeared.
