Random Surprises and Functions

A screenshot of the Scratch programming interface, showing a project named “Pufferfish Puff.” The stage area on the right displays an underwater scene with multiple pufferfish sprites scattered across it. The code area in the center shows a set of code blocks. The main block is a custom “define cloneAndScatter” block. Inside this block, a pufferfish sprite is configured to: set its size to 50% show itself repeat 10 times, it will: switch its costume to a random choice from 1 to 4 go to a random position on the screen point in a random direction from 0 to 359 degrees create a clone of itself finally, it hides the original sprite. On the left, the “Looks” code palette is selected, showing blocks like switch costume to, next costume, and others. Below the stage area, the “Pufferfish” sprite is selected, showing its current coordinates, size, and direction.
