The Nitro Switch Crate is a type of crate that appears throughout the series. They appear as green-colored ! crates, and show up only once per level. When attacked, they destroy all the remaining nitro crates in the level. They are needed for box completion due to the need to destroy the nitro crates. In Crash Twinsanity they are initially replaced by detonator crates, but two nitro switch crates can be found in Cavern Catastrophe which explode every nitro crate nearby. In this game it turned into the shape of a nitro crate before exploding the crates.
