Crates marked with a "C" are checkpoints that Crash will return to if he is killed during play. Locked Crates are protected by a metal casing that can only be destroyed with Crash's body slam move, while Spring Crates allow him to reach high up areas by bouncing on them. Slot Boxes rapidly switch between multiple types of crates, and if they are not broken in time, will become metallic and indestructible. Time Boxes are a special crate found exclusively in Time Trial mode. They will freeze the clock for the number of seconds displayed on the box, increasing the player's chance of beating the time trial.
