When you are inside a cog building and have defeated the cogs on that floor, the next elevator will open to take you to the next floor. If you have over three Toons with you, try to be the third or fourth Toon to enter the elevator. This will place you in the front row of the elevator. Before the screen cuts to the part where the elevator goes up, use the emotion "Angry". Your head will go through the elevator. Note that this can work when your Toon is close to most walls.
