why won't my turtle move

[ironsheep]

Now things are getting weird, I did do fred=turtle.Turtle(), but now a third arrow has appeared---- you have to test the program out yourself--- I always thought = means "is a", but now everything's gone weird.

import turtle
emily=turtle.Pen()
emily.shape("turtle")
emily.color("purple")
emily=turtle.Turtle()
emily.forward(100)
turtle.forward(300)

I still don't understand why my computer didn't understand my first commands on my first post---- Fred is clearly the turtle and should be moving, it is so obvious even the computer knows that fred "is a" turtle.
