You need to have loaded the StarSqueak package.
Put the following code in a Workspace and evaluate it.
StarSqueakAntColony new openInWorld
Open the menu of the morph and keep it up. Choose 'start' from the morph's menu. You see a simulation of an ant colony with ants reaching out for food.
StarSqueakForestFire new openInWorld
StarSqueakTurtles are used in this simulation.
