At regular intervals, the Signal Floor will change color. Every Signal in a stage is synced up so that they all change colors simultaneously, but they may not all be the same color at the same time. The colors cycle through the following order: In Super Bomberman 4, all enemies can pass freely through the Signal Floor regardless of its color, but in Super Bomberman 5, they may only pass through when it is blue. In the latter game, it is possible to place bombs on blue Signal Floors, and explosions do pass over them when they are blue.
