[Squeakland] OLPC pen trails for turtle graphics

I'm just about to start my own kids off on some OLPC Etoys
investigation, so I had a quick play, intending to make some turtle
style polygons. It didn't work as I expected.
A simple script like this:
Repeat 2 times
Star forward by 100
Star turn by 90
did not leave an L shape trail as I expected, but a diagonal line from
the start to the finish position.
Is this how pen trails are supposed to work? How do I draw a classic
polygon, where the start and finish positions are the same?
Currently no pen trail is left at all.
