1) Click 'See inside'. 2) Three variables (Penguin Paul/Score, Penguin Penny/Score and Time) have already been set up. You need to code the first penguin: it moves up and down when the keys 'a' or 'z' are pressed and you can find here the sound effect and score change too. 3) Copy the code onto the second penguin. This should move when the up/down arrow keys are pressed. Mind that here Penguin Penny's score must be changed. 4) Finally, put the code for the ball in order: The first part is about its movement, the second part is about the time. Good coding!
