when the bubles move out of the window, how can we make the bubble go all the way down and appear up again in the window? Thank you

bubble is actually a circle. So you can try getP1().getY() to know the location of the bubble. If the location is equal to 0, which means the bubble reaches the top of the window. then you can do self.circle.move(0, WINDOW_HEIGHT) to make the circle wrap around.

Yes, like Thu said, you will basically teleport it to the bottom of the window again when it reaches the top, so it appears to simply wrap around the window.
