Snot Land
Despite this area being a snot filled swimming pool there are a few things to do before venturing out.
If Jeff's IQ is over 45, you can fix the Broken Bazooka.
You can load up on more Multi Bottle Rockets, because they go boom boom bang really good.
Talk to the Monkey to get some Monkey's Love......
Get some free medical care.... ( highly recommended if you want a cool easter egg type thing at the ending of the game ). Just tell him that he can cover the tab.
