On the Spliterz Manufacturing level, there's a way to get into the Glukkon Executive Office. After the big bro slig wipes everyone out past the voicelock, have munch drink some bounce and take him to the front of the office. Abe can throw Munch to the platform he would stand on to possess the Glukkon. Now that Munch is on the platform, the door is open and you can run inside the office...for a couple seconds then you get killed by the security system!
You die, but it's fun!
