Fake Blocks appear in plain grasslands and Airship levels. They appear alongside regular Brick Blocks, but are noticeable by their darker tone. If Mario or Luigi get close, it will reveal itself and jump after him, swinging its tail if it gets too close. They can be defeated with the swing of a Tanooki tail, a Ground Pound, or by jumping up and breaking the block, though the latter only works when it is not active.
