    Step 2:  Choose a background from “Choose a Backdrop icon”, e.g. “Underwater 2”
                                   from the “Underwater” tab in the “Choose background” window. (Shown in

                                   Fig. 9.1)

                                                 Fig. 9.1: A glimpse of Fish floating in water.
                       Step 3:  Click on the “Events” block and drag “when flag clicked” block into the
                                   script area.

                       Step 4:  From “Looks” block choose “switch costume to…” block in the script
                                   area  and  select  the  value  “fish-c”.  (You  can  choose  any  other  fish

                                   costume of your choice.)
                       Step 5:  From the “Control” block choose “forever” block in the script area, to
                                   repeat the fish’s floating action continuously (i.e., forever).

                       Step 6:  From the “Motion” block, choose “glide... secs to random position” block
                                   in the script area. Change the value 1

                                   to any other number (e.g., 10) to make
                                   the  fish  float  slowly  and  naturally  in
                                   the water to a random position. Also,
                                   there is no need to wait now, as  we

                                   don’t need to stop fish now.
                       Step 7:  When  we  click  on  the  flag  now,  fish

                                   will  floats  continuously  or  forever  in
                                   water. (See the code in Fig. 9.2).                             Fig. 9.2
