Koala Lumpur - Journey to the Edge

Hint:
-----
Can't get Dingo (that stupid dog stuck in the fridge) out? 

Here's the way: 
i) Go to the lab using the elevator. Locked? 
Get the keys from one of the books. The books can be found 
in the bookshelf beside the fridge. The books are under a 
kind of cover. The books are very important. Bring 'em along.
ii)Inside the lab, dark huh? Switch the lights
on. If you look around, you'll find undergarments. Take the
yellow shirt which has a bones as a pattern. Go to the computer
which reads DINGOS. The password is "steamer" or "pungent" i 
can't remember. After you access the computer, go to a kind 
of password translator. Select the password which looks like 
a horizontal 8. Type 'PEMEMEZ'. 
Click the button which reads as '??->!!'.
That should change it to "BANANAS"
