Boiler Room Doom (レッツゴーボイラー lit. Let's Go Boiler in Japanese) is the ninth level of Crash Twinsanity and it is the first level in the Academy of Evil. It is accessed by a secret passage hidden in the fountain. To pass it, Crash must throw Cortex into the machines that stick him in a pipe. Bugs are abundant here and on two occasions players can find red bats. The boss of this level is Dingodile. At times in this level Crash must also connect pipes for Cortex in order to progress through the level. The pipe puzzles usually get bigger and more complicated for Crash to complete, such as in the Vent and Fan Rooms (second-to-last and last puzzle rooms, respectively), where he must spin blue wheels that activate platforms to other blue wheels that complete the pipeline.
