You're lost in the desert.
Furthermore, you are surrounded by black turtles and even under your feet stands a turtle.
But then again, after a few minutes of hard thinking, you've got the solution !
You can play a game with the turtles !
Cause, when you jump on another nearby turtle, all turtles around that turtle run away while, at the same time, some turtles come stand close to you on the vacant spots with great curiosity !
