Which levers do what?

As you should have worked out by now - the first lever is a dual-purpose lever,

operating two platforms and trapping Lenny on a floating platform.

Now. Go up the first ladder and turn left. Go up again and turn right. Keep

walking to your right and you will see that the next lever you come across is

a multi-purpose one. Pulling it will extend some bridges but retract others.

Look at the red and green lights to determine what bridges the lever has activated.

What do the red and green colored lights on the pipes and levers mean?

So, after you pull that lever walk along further to the right. Eventually you

will come to another lever. Only click here if you want to cheat and find

out what this lever activates!

After you have discovered what the above lever does you will be able to

make your way down and to the left until you come to the lever which

extends the other bridge.
