Cut and paste these examples into Pippy and save then to your Sugar Journal. Then use the Load-strategy button in Turtle in a Pond to try them.

In this strategy, the turtle moves down, regardless of whether the dot is open.

In this strategy, the turtle moves down until it is blocked (i.e., when the dot type s True).

If it tries to continue in the direction it was already heading, the turtle is harder to catch.
