#

The variable name is not declared as a field within the class, so, again, the compiler cannot find it.

something like... leavesEaten = 0;

I suggest you check out the Java tutorial page on Declaring Member Variables in the Classes and Objects trail. Something like:

import greenfoot.*;

public class Wombat extends Animal
{
    private int leavesEaten = 0; // declare it here

    public void act()
    {
        // etc.

In the Wombat class, remove lines 33 and 34 (you did not have anything like that to begin with; and I think they were given as example code). Next, change lines 49 through 53 to the following:

if (leavesEaten == 6)
{
    GameOver(leavesEaten);
}

Also, you should probably do something about the redundancy of the code in your 'lookForAnt' method (which is similar, but different, in the act method). Maybe by changing the method name to 'lookForFood' and adding line 14 within the method and replacing lines 10 through 21 with 'lookForFood();'.
