Crate Balls of Fire (ひのたま きゅうせっきん！ lit. Fireball Approaching Rapidly! in Japanese) is the penultimate twenty-fourth level and is the fourth level of the fifth warp room of Crash Bandicoot: The Wrath of Cortex.
It takes place in space, probably on some space station. It looks similar to the level Droid Void and this level also contains a chase, where Crash is running from a massive fireball while wearing his mech suit. Enemies of this level are robots and exploding bombs.
The level's name is a portmanteau of the word "crate" and the phrase "Great balls of fire!", which was often used in the past as a replacement for "Oh my God!"
The name could be a reference to the group Earth, Wind and Fire. Moreover, the game is based on The Elementals.
It could also be a reference to the 1957 song, "Great Balls of Fire", by Jerry Lee Lewis.
Although Py-Ro has been defeated in the third Warp Room's boss fight, he still causes the fire chasing Crash in this level.
