Deep Trouble

Deep Trouble (かいていの うずうずマシーン lit. Whirlpool Machines Undersea in Japanese) is the twelfth level and is the second level of the third warp room in Crash Bandicoot: Warped and its HD remake, N. Sane Trilogy. It is an underwater-themed level similar to Under Pressure from the first warp room chamber, but due to the added TNT crates and Nitro crates and increased hazards, it's much harder. There are also mines, sharks, pufferfish and whirlpool-making machines. In this level, Crash can collect the red gem. To obtain the red gem as well as the clear gem, Crash must activate the ! crate at the end of the level and go back to the split path. A TNT crate that wasn't there from the start should appear from an outline crate, allowing Crash to activate its timer, and opening a passage after it blows up. Then he will enter the special route of the level that relinquishes the red gem, the nitro switch crate, and some other crates. The submergible is used again in this level.

Just like the other swimming levels in the remake, Coco cannot visit this level.

Name origin
The name of the level may be a reference to the phrase "in deep trouble", which is used to describe someone that is in a high level of trouble. The "Deep" part may refer to Crash exploring the deep part of the ocean, while "Trouble" could refer to all the enemies and obstacles in the level.

Trivia

 * Despite the fact that there is a special path in this level, no music was made for it. This is unlike the previous game, where secret paths that aren't accessed through riding a platform (for example, The Eel Deal) also change music.
 * This is the only level out of Cortex Strikes Back, Warped and The Wrath of Cortex where the path which leads to a colored gem is also required for box completion.
 * This is the second underwater level in the game and series. The first in this game is Under Pressure.
 * There's a minor glitch with the crate tower in the secret area. The two basic crates above the TNT crate on top of the left pile are not opened by the explosion, they are blasted into the rock formation above before landing onto the sea floor.
 * According to an unofficial guide, this level used to have 88 crates, instead of 83.
 * This is the only level in this game to have two box counters, even though it's not the only level with two exits, like Piston It Away in the previous game, which also requires backtracking the main path and entering the special route. However, since it is actually possible to backtrack to the first box counter in this instance, Deep Trouble is the only level in the series where the box clear gem can be recovered from two distinct locations.
