Classroom Chaos

Classroom Chaos (メチャクチャクラスルーム lit. Messed Classroom in Japanese) is the eleventh level in Crash Twinsanity, the second in the Academy of Evil and the only stage where Cortex goes solo for part of the level. It continues on from Boiler Room Doom. The level is very easy for collecting Gems, as they are all pretty much on the main path. Next to Ant Agony and Totem Hokum, it is considered one of the longest levels in the game.

Description
The level starts off as Crash. The player must make their way through several corridors and classrooms and at one point outside where three Guard Dogs await. In certain corridors, there are Hall Monitors which Crash has to hide from, similarly to the Tribesmen in Totem Hokum, looking out for intruders. Eventually, Crash makes it to a library that is filling up fast with green acid, possibly from the underground boiler room. Crash has to make it to the top before he is killed by it.

In the next segment, the player takes control of Cortex, who takes over and tells Crash to go back to the Airship and tie it's ropes to something secure. Like Crash, he has to make his way through classrooms and corridors to reach Nina's dormitory. He uses his Ray Gun to deal with Robot Dummies and monstrous Robotic Janitors, for which he has to ring a bell and students run out trampling it. In certain corridors, Cortex will be chased by beetles and in certain classrooms Cortex will have to defeat test frogs and mice to progress.

Finally, Cortex makes it to Nina's dormitory where Rooftop Rampage begins.
