The first case involving Mr. Collingwood was after he had given his class the S.A.T.T.Y. 9 test, he was seen in the school's hallway wheeling boxes of answer sheets for the test. There he met the school's mascot, Lobstee the Lobster, or at least someone wearing the outfit, who then stole the answer sheets and ran off with them. Which was when Mr. Collingwood phoned for help from the Safety Patrol.
He has also been known to direct a school plays.
