Write and run the program

Display Figure 1.

The drill team marches in a square ending up back where they started.

Create a new world and populate it with three penguins and three cows as you see in Figure 1.

Rename the penguins penguin1, penguin2, and penguin3.

Rename the cows cow1, cow2, and cow3.

Don't be concerned about their initial positions.

That will be taken care of in software when the program first starts running.

Rename the default method to main.
