Weak platforms are platforms that appear in the final level of Crash Twinsanity, Ant Agony. They are purple in color and considerably smaller than sequence platforms (which also appear in the level). Weak platforms disintegrate shortly after being stepped on, and Crash must hop from platform to platform in many areas of the level.
They usually appear when the player steps on a switch, often moving horizontally. The player must use them to reach the other side of the pit. At one point in the level, when Crash steps on a switch, they come out of the wall towards him. When Crash steps off of the switch, the platforms slowly glide back into the wall. Crash must stand on the switch and allow the platforms to move out, and then jump across them as they glide back towards the wall before they are gone.
