    Step 3:  Choose any 2 backgrounds from the “choose a backdrop” icon. e.g., like
                                  Basketball 1 and Basketball 2.

                       Step 4:  From the “Looks” block we will drag the “switch backdrop to…” block
                                  and join the block with above. Now choose “Basketball 2” value for

                                  background. This will change the background of stag to “basketball 2”
                                  when we click on the flag. But this will not be seen by us when we move
                                  to the next background. So, from the “Control” block, we will choose
                                  the “wait for 1 seconds” block to wait for a few seconds with this

                                  background before moving to the next background.
                       Step 5:  Again, from “Looks” block we will drag the “switch backdrop to…” block

                                  and join with the above block and then choose Basketball 1 value OR
                                  drag “next backdrop” block instead of above block.

                       So, now every time when you click on Flag, it will change the background 2 times.
