Continue allows you to control the flow of your loop by skipping the current iteration and returning back to the beginning of the loop. In your example, when you get into the loop, you are immediately taken out of it because of continue, however, because true is still "true", you are in an infinite loop that just keeps taking you out the iteration and starting back at the beginning. If something were to, for example, change the true value to false, it would go back to the beginning of loop, see that true is now false and be able to print out "Croak". 

bool example = true;

            while (example)
            {
                example = false;
                continue;
                Console.WriteLine("Ribbit");

            }

            Console.WriteLine("Croak");
