Aunt Murgatroyd is back to challenge potential problem solvers with more riddles, puzzles and problems! This time the Troublemaking Trolls are looking to remove one of the most helpful pieces of punctuation, the comma! See if you can figure out where and when to use a comma in order to know where and when the Trolls will strike. And then solve the Million Dollar Comma Challenge to thwart their efforts for good and sentence the Trolls to another defeat.
