getX(), getY() From Different Actor

So I have an enemy that tries to attack my main character: Jellie. It is supposed to follow Jellie by constantly facing it. However, I used Jellie.getX(), and Jellie.getY(), and I got the error message; "non-static method getX(), cannot be referenced from a static context." How would I go about getting Jellie's X and Y to the Baddie?

Jellie is the name of your class. It is not the name of any Actor created from the class. It is the TYPE of actor created from the class. A class (or TYPE) does not have a location within any world. The actors created from the class will have location coordinates when added into a world. 
// the following line will error:
int jellieX = Jellie.getX();
// but these lines will not:
Jellie jellie = new Jellie;
addObject(jellie, 0, 0);
int jellieX = jellie.getX();
Here, line 4 creates a Jellie actor and assigns the object to a local variable names 'jellie'. 'Jellie' refers to the class (or TYPE) and 'jellie' refers to the actor created from the class. I will presume you only have one Jellie object in the world and it can be referenced from an actor class with the following: 
if (! getWorld().getObjects(Jellie.class).isEmpty())
{
    Actor jellie = (Actor)getWorld().getObjects(Jellie.class).get(0);
    int jellieX = jellie.getX();
    // etc.
Here, line 1 ensures that a Jellie object IS in the world so that we do not try to get a non-existent element from the list on line 3.
