The Torture Chamber is a secret room in Adu Du's Spaceship where he is supposed to torture BoBoiBoy but Probe and Computer decorated it into a party Room instead which made him angry.
But soon they still continue to torture BoBoiBoy by blowing all the balloons which scared him until he evolved to BoBoiBoy Thunderstorm.
So far it only appeared in Season 1, Episode 6.
