Metal Platforms are a 'wall' that can move around on various angles and directions when activated by Triggers. They can push fluids and balloons, and fluids (but ooze) can bounce off them and be redirected somewhere else. They are the most common thing to be activated by Triggers. They are made from coloured boxes and will always be square or rectangular. Light Blue ones controlled by the player are known as gates, which are similar to Metal Platforms.
