Board notes 5 details

Layout: Astrodog floats at the left with his mouth open; a tall gray vent pipe blocks the center-right, a smaller grille sits above it, and blue bubbles float around both obstacles.
Goal: Clear both ventilation obstacles from the bubble's route and let the water drift into Astrodog's mouth.
Opening: Move the tall vertical pipe away from the approaching blue bubble, then reposition the small grille when it blocks the same line.
Danger Zone: Dragging the bubble itself does not solve the level, and moving only one vent can leave the other gray piece in its path.
Mechanics: The water bubble drifts automatically; the player controls the tall pipe and small grille that obstruct its route.
