Norman Hedgehog

Unknown Male Rat is an unnamed character. He is mostly seen either at lunch or in the hallways of Lakewood. Very little is known about this character although he has had one speaking role out of the whole series, which was in the episode Arthur and the Crunch Cereal Contest.

It's possible he might be a fourth grader since it could be him that's in the picture seen in the episode Brain's Shocking Secret. He is mostly a background character and as for his personality he seems generally nice. He hangs out with both third and fourth graders, but hangs out with 3rd Grade Male Rat most of the time.

Appearance
Unknown Male Rat is a light gray rat that wears a light orange collared shirt with long sleeves, blue jeans, and orange shoes with white stripes. He has short brown hair that runs from the top of his head all the way to the back of his neck.
