FLAPPY HAPPY BIRD

and upload the other “Flappy” files and name them “costume1”, “costume2”, etc. up to 6.

5. Upload “punch” (sound) 6. Upload “flappy” (sound) 7. Upload “flappy bird theme song” (sound) 8. Now start dragging and dropping code to create code

blocks for Flappy until they look exactly like the following examples.

9. The graphic in the upper left of the following pages shows which sprite you should be creating code for.
