Secret Places (4)
This is a very clever secret. It's in a corner of the red room which blows up and collapses. The hidden door opens after a somewhat lengthy period of time... or at least it seems lengthy when you're dodging explosions and trying to survive. If you can afford to lose approximately 50 health, curl into the fetal position and hide in the corner as in the image. The hidden door will open soon before the ceiling completely collapses. If you'd prefer to keep your health, wait in the bright area by the enforcer and watch the corner of the red room. As soon as it opens make a dash for it. Inside this secret you'll find Homer Simpson's work station (sector 7-G).
This is the room next to the trash compactor trap. Press on the computer to open a hidden door.
Go to the nuclear core with the enormous cylinders. There are a few explosive canisters next to one of the walls. Blow them up to find a secret area.
Fly to the top of the nuclear core and look around for a secret crevice containing a shrinker.
