Light blue blocks

Light blue blocks are interactive objects in the game Headcase. They are designed to work with blue switches.

Appearance
Light blue blocks are light blue squares, hence the name, and have rounded corners. When extended, a grey-blue screw is also seen holding the block. Gears can be seen in the cavity where the blocks were.

Game information
Light blue blocks will remain shut until the player presses a blue switch, at which point they will move forward or backward, depending on their position, to open or close access to certain areas. They have to be opened to complete levels, and can kill Norman Noggin if he gets squished.
