Unknown Male Sheep

"3rd Grade Male Sheep" is an unnamed character that appears in "D.W.'s Library Card". He stands in the line to check out books when D.W. is asking for the first time if Hopalong The Frog has been returned yet.

He looks similar to 3rd Grade Female Sheep, just like Aloysius Zimmerplotz looks like 3rd Grade Female Cat. In fact, both are male dopplegangers of female 3rd graders that only appear in "D.W.'s Library Card".
