H2 Oh No

H2 Oh No! is the tenth level in Crash Bandicoot: The Wrath of Cortex. The first part of the level takes place underwater, where Crash maneuvers a submarine (like in the second part of Sea Shell Shenanigans and the first part of Coral Canyon), shooting enemies and breaking crates. The second part of the level takes place in a damp cave, where Crash traverses on foot, spinning lab enemies and crossing pits of green electrical fluid on iron crates.

Trivia

 * The name of the level is a play on "H2O," the chemical formula for the biological compound water (2 Hydrogen atoms and 1 Oxygen atom).
