11.  Halloween --

Unlocks Skeleton Costume
Unlocks mission 'Help Gary'
Unlocks side mission 'The Big Prank'
Unlocks side mission 'Character Sheets'

When you get back to the dorm, you'll find Gary lying on your bed in a 
military uniform.  He'll tell you he's left a costume in your closet for
you.  Step into the marker by your closet to change clothes and start this
mission.  This mission has some really cool features to it that you need to 
be aware of before you begin to get under way.  First of all, time is at 
this point standing still.  The clock in the upper left corner of your 
screen disappears and you don't have to worry about making it to bed on time
or precepts or anything.  All the precepts are at a party and there will be 
none to be found anywhere.  Feel free to use this time to enter the main 
school building and break into lockers at will, because nobody will be there
to bust you.  You will also notice that spread around the campus there are
pumpkins glowing brightly in celebration of the holiday.  To be precise, 
there are 27 pumpkins and smashing all 27 of them will award you with a 
secret surprise.  In addition to the pumpkins, you will also notice 
tombstones on various pieces of grass about the campus as well.  19 tomb-
stones in all.  Again, destroying all 19 tombstones rewards you with yet 
another secret.  After completing this mission, and the holiday is over, 
these items will be put away and stored in the basement of the main school
building where you can get to them later if you choose not to get them at
this time.  Your time is unlimited here, so you might as well.  For further
information on the pumpkins and tombstones, please see the "Extras and 
Secrets" section of this walkthrough.  If for some reason, Gary and Pete get
taken out of the picture during the course of your campus wide vandalism
spree, fear not, because they don't need to be with you to complete 
'Halloween'.  --On to the mission itself. . .Spread about campus are six 
students that want you to play pranks for them.  These students are 
indicated on your mini map by a blue "X".  In the bottom right corner of
your screen you will see that the number of pranks you need to complete only
amounts to five, so you won't have to do all of them.  Simply find the 
student in need, target them with L1 and then press "X" to accept they 
prank they ask of you.  Each student will provide you with the necessary 
"tool of malice" required to complete the prank.  The pranks are as follows:

Put a "Kick Me" sign on a student --  simple enough, with the "Kick Me" sign
in hand, creep up behind ANY student, target him with L1 and press the
square button to slap the sign on his back.  Watch with glee as the student
gets kicked, and you get credit for having completed a prank.

Throw Itching Powder at three students -- Very simple, and you barely have
to move.  With the Itching Powder armed, simply target a student with L1
and push the R1 button to throw it at them.  They itch, you laugh and you
move on to the next.

Egg three students -- See above prank.  Same thing, just with eggs and 
without the itch.

Trip one student with marbles -- Once again, pretty much the same concept
as the above two pranks, only you only have to do it to one student.

Hit three students with Stink Bombs --  Yeah, I know, the concept is getting
a little tiresome now, isn't it?

Light Volcano 4000 near some students --  Ok, well, at least this one is a 
little different.  Find two or three students standing around and walk up
to them with this little beauty in your hand.  Light and drop it near the 
students using the on screen instructions.  The students will "OOOOOHH" and
"AAAAH" at the pretty fireworks, and when it's done, it will explode and 
knock them all on their ass.  Pretty funny.

When you have completed any 5 of the above pranks, the mission is complete
and your clock returns to the upper left hand corner of your screen.

**IMPORTANT!!**
Completing this mission unlocks two side missions, 'The Big Prank' and 
'Character Sheets'.  Of those two, 'The Big Prank' is ONLY available on 
Halloween night, so if you choose to skip it and go back to the dorm and go
to bed, it will be lost forever and you can not go back and do it later.
It is NOT . . .let me repeat, NOT required to get 100% completion in the 
game, however when the clock reappears on the screen after completing 
'Halloween', it is only 9:00 pm and 'The Big Prank' is a very short, very 
easy mission should you decide to do it for the giggle.  I did it on the
first time through and was back in my dorm room getting ready for bed at
10:00 pm.
