The Big TNT is a rare crate that was featured in Crash Bandicoot as the object required to defeat Ripper Roo. It's obviously much bigger than a normal TNT crate and it also has the text Big TNT painted on.
Just like at a normal TNT crate, jumping on it will give Crash three seconds to get away, after which it explodes. The Big TNT explodes with a larger radius than the normal TNT and it also doesn't count down from 3-2-1. When Crash jumps on the crate, it starts to flash after each second, until it goes boom.
