12 - To the rock!

Take the boat to the rock.

Beware, the boat may randomly stand on any of the darker tiles at the beginning.

When you start the program, the boat will jump to another darker tile before executing the program.

Try: run your program several times in a row and you will see that the ship starts on different tiles.
Your program must work for all the start tiles.

Hint: some menu blocks contain drop-down lists that can be clicked.
The barrier block tests if there is a rock on the tile in front of the boat or not.
