Proximity Crates are cut crates from Crash Bandicoot: The Wrath of Cortex and their purpose is unknown. They can be found in the game with the use of cheat codes. When broken, they do nothing. These were probably used to change the course of Crash's minecart in some levels. One theory suggests that they were supposed to activate platform lifts. This is because there's an activator for moving platforms with a name that starts with "proximity". However. it doesn't work when you get close to it. Another theory implies that they could be one of the elemental crates that have been mentioned in several articles before the game's release.
