4 Blocks that act like reversed switch palace blocks.
They are solid, as long as the switch is not pressed and become pass through able once they have been pressed. You should make them act like 25
Comes along with a Manual Trigger Block and an ExGFX file to give the blocks a better appearence.
Since the last block changes the way the other blocks look but doesn't interact with Mario, it should act like 25, be invisible and be placed right at the beginning of the level (midpoint).
