Red Bricks
From the Croc Wiki, the Croc encyclopedia
In some levels, a line of Red Bricks will often hover over a Pit. If Croc steps on any part of the line of Bricks, the whole line will fall in a few seconds, which will then respawn after a few seconds. It is similar in function to the Unstable Platform. In the level The Tumbling Dantini, the Red Bricks do not hover over a deadly Pit, but actually requires Croc to stand in the middle and wait for it to fall in order to land on a Smash Box to get a Gobbo.
