Fish hit by a Star.
After the Star rises, before returning to the bottom, you need to use a touch. . . block to determine whether it hits the

When the Star sprite hits the Fish sprite, we need to tell the Fish sprite about this and let it do the corresponding
behavior-change its shape.
We set up a “Hit” broadcast. This broadcast will tell the entire program that something called “Hit” has happened. All
sprite and even the backdrop can hear this broadcast and respond accordingly.
