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
