Wally P. Rectangle, more commonly known as Mr. Rectangle, is a rectangle who often plays the role of a villain, usually accompanied by his assistant, Mr. Diamond. He debuts in Issac, Tyler, and Gabriel as the owner of a successful chocolate waffle factory who tries to force his employees to bow down to a giant waffle. Mr. Rectangle later learns his lesson when the Lord miraculously saves Issac, Tyler, and Gabriel (a few of his employees) when he throws them into the toaster for not worshiping the idol. Wally P. Rectangle has a twin brother, Nebby K. Rectangle, who has a similar villainous stance in The Mater That Surfed Christmas.
