Cavern Catastrophe

Cavern Catastrophe (ありンコキリキリまいった！ lit. Ants Coming at Full Force! in Japanese) is the third level in Crash Twinsanity and the third level on N. Sanity Island. It takes place after Mecha Bandicoot has been defeated, and features Crash and Cortex in a rollerbrawl. This level contains the first crystal in the game. This is the first level to feature Crash and Cortex in a rollerbrawl.

Description
This level features Crash and Cortex in a rollerbrawl going through some mines in the huge cave systems of N. Sanity Island. A common hazard in this level is Nitro Crates which are placed on the tracks in stacks. While most of the level involves Crash and Cortex in a rollerbrawl, a few segments involve Crash and Cortex joined. This level also features an exclusive gameplay feature; color varying-crystal clusters that Crash and Cortex must roll into or spin in order to make rocks fall from the cave ceiling which aids the player's progress. The level features a battle against the Ant Drones and later on, a chase where Crash and Cortex are pursued by the Ants' drill vehicle. A very interesting thing to note is the inclusion of two Nitro Switch Crates in this level, which appear nowhere else in the game. Their function is to blow up distant Nitro rather than destroying all of the Nitro in the level. It contains several gems and information on their locations can be found here.

Pitfall
Pitfalls are the main hazard of this level, since almost all of the time they surround the playing space.

Nitro Crates
Nitro Crates are very common in this level, usually in stacks of up to three.

Ants
The Ants in this level can attack Crash by charging him or attacking him with a laser sword, but they can be defeated easily.

Gas sprayers
Gas sprayers are very often found in this level. Crash and Cortex will have to roll through them when they are not spraying.

Bombs (Removed)
In the demo version of the game, one of the wheels would have bombs rolling into it, so Crash and Cortex would have to time their entrance into the wheel.

Bats (Removed)
Also, in the demo version of the game, several bats would attack them if they stayed in one place for too long.

Rats
Rats, however, do not block the main pathway, but they do guard the Blue Gem of the level. It is easiest just to throw Cortex to get the Gem.

Drill
Crash and Cortex will have to escape the Ants' drill in a Chase sequence. To slow it down, the player must spin three crystal clusters in order to make rocks fall onto it.

Beta elements
The demo version of this level had a lot of different placements, and as mentioned before, the inclusion of Bats and Bombs in the level. The level had a changed layout also.

Trivia

 * This is the only level in the game to contain a Nitro Switch Crate, both of which blow up the same Nitro Crates (though this is probably unintended).
 * N. Gin's "Cutscene Model" can be found hidden at the start of Cavern Catastrophe.
 * This is the only time in the game where the player gets to control Crash and Cortex in a rollerbrawl manner.
 * The third-to-last acid pit in the level can be jumped over without destroying any Nitro Crates.
