Jack Weasel

4th Grade Male Rat is an unnamed fourth grader. He is seen mostly at both lunch and the hallways of Lakewood. He is most of the time used as a background or cameo character.

He hasn't had a speaking role yet. As for any friends he hangs out with third graders and fourth graders just like the main and minor characters.

He mostly hangs out with the 4th Grade Male Rat (Number 2). He is generally nice to the kids and is in the same fourth grade class as Prunella, though it's unknown if he is friends with Prunella.

Not only that he was in the same kindergarden class as Prunella and most if not all of the other unnamed fourth graders that were in the kindergarden class.
