I know nothing of TurtleWorld but...

Thats what I'd expect...

Thats also what I'd expect since you have created a turtle but not
drawn anything yet.

Check the methjods, you may need to make the turtle visible,
put the pen down, and move it around a bit.

If pen down is default(it usually is) try doing

bob.forward(50)

Does that do anything?

Presumably thre are some drawing examples in the book...
