Halloween is almost here, the holiday after which most people need to wean themselves off a hollow diet of sugar.

Write a program that takes in a positive integer. If the integer is less than 31 (1 through 30), output this ASCII-art jack-o'-lantern, looking to the right as if looking forward to Halloween:

 _____I_____
| | | | | | |
| | |^| |^| |
| | | |^| | |
| | |VvVvV| |
|_|_|_|_|_|_|

If the input is 31 (the October date Halloween is on), output the same ASCII-o'-lantern, but looking left:

 _____I_____
| | | | | | |
| |^| |^| | |
| | |^| | | |
| |VvVvV| | |
|_|_|_|_|_|_|

If the input is greater than 31, output a bloated-looking ASCII-o'-lantern who probably ate too much candy. He can face either left or right since queasyness can be disorientating. So output:

 _____I_____
| | | | | | |
| |o| |o| | |
| | |^| | | |
| |XXXXX| | |
|_|_|_|_|_|_|

or

 _____I_____
| | | | | | |
| | |o| |o| |
| | | |^| | |
| | |XXXXX| |
|_|_|_|_|_|_|

Whichever you prefer. It may even be different for different numbers above 31.

The shortest code in bytes wins.

Note: This code does not work in the most recent commit as of posting, because string indexing is broken. It should, however, work in this version from October 25. It also runs successfully on the version currently on Try It Online.

Explanation

Charcoal is a language designed for ASCII-art. Output is put onto a canvas, which is printed at the end of the program.

Setup

Get input and calculate face characters:

Nβ        Input number into beta
A‹β³²τ    Assign beta<32 to tau for easy reuse
A§o^τε    Assign appropriate eye character (selected via indexing into "o^") to epsilon
A§XVτφ    Assign outside and middle mouth character to phi
A§Xvτθ    Assign other mouth character to theta

Draw the pumpkin

F³«  »    Do this three times:
P↑⁵       Draw a 5-character line upward (using | by default); don't move the cursor
|_         Draw that string, rightward

After this loop, we have

| | | 
| | | 
| | | 
| | | 
|_|_|_

Next:

↑⁵         Draw a 5-character line upward
←I         Draw the stem leftward
←×_⁵       Draw 5 underscores leftward
‖O→       Reflect the canvas rightward, overlapping in the middle

Result:

 _____I_____ 
| | | | | | |
| | | | | | |
| | | | | | |
| | | | | | |
|_|_|_|_|_|_|

Draw the face

We will draw the face looking rightward and change it later if necessary.

↙↙←←ε      Move to the correct spot and draw the right eye (our right, pumpkin's left)
↙←^        Move to the correct spot and draw the nose
↖↓ε        Move to the correct spot and draw the left eye
↓→φθφθφ    Move to the correct spot and draw the mouth with alternating characters

Result (for input 31):

 _____I_____ 
| | | | | | |
| | |^| |^| |
| | | |^| | |
| | |VvVvV| |
|_|_|_|_|_|_|

Reflect if it's Halloween:

¿⁼β³¹      If beta equals 31:
‖←         Reflect canvas leftward

Final output:

 _____I_____ 
| | | | | | |
| |^| |^| | |
| | |^| | | |
| |VvVvV| | |
|_|_|_|_|_|_|

I'm dissapointed with how long this turned out. It is more convoluted than usual since V can barely handle numbers, a lot of bytes come from creating hacky conditionals.

As Titus mentioned, I can save some size with i < 32 instead of i in 1..31

Removed all possible spaces around operators... Forgot to do so in the beginning

Rewrote ternary conditions to use the saved variable, replaced ; with newlines, removed explicit variable definition

As Otávio mentioned, I can save another 4 bytes if I switch from | |${j ? ' |^| | ' : ' | |^| '}| | to | | |${j ? '^| ' : ' |^'}| | |

Now shamelessly stealing @ETHproduction's trick for positioning the face. Encoding: 0 is an eye, 1 and 2 are teeth, 3 is the left side, 4 is the right side and 5 is the bridge of the nose.

Ruby, 168 bytes

->i{s=(Zlib.inflate Base64.decode64 "eJxTiAcBTzDJVaOABCG8OCiGycUhyYWVASGYF48EuRTwGhmHZkgckhzMQBKNzIdibEZGgAA2IwFZA1N4").lines;puts i<31?s[0..5]:i<32?s[6..11]:s[12..17]}

Probably far from optimal. Requires the base64 and zlib libraries.

Call as a lambda function.

C# 6, 223 215 bytes

int d=int.Parse(args[0]);var x="| | |\n| |";var s=d<31?" |^| |^| |\n| | | |^"+x+" |VvVvV":(d==31?"^| |^"+x+" |^| "+x+"VvVvV| ":"o| |o"+x+" |^| "+x+"XXXXX| ");Write(" _____I_____\n| | | | "+x+s+"| |\n|_|_|_|_|_|_|");

Entire program ungolfed:

using static System.Console;
namespace Halloween
{
    public class Program
    {
        public static void Main(string[] args)
        {
            int d = int.Parse(args[0]);
            var x = "| | |\n| |";
            var s = d < 31 ? " |^| |^| |\n| | | |^" + x + " |VvVvV" 
                           : (d == 31 ? "^| |^" + x + " |^| " + x + "VvVvV| " 
                                      : "o| |o" + x + " |^| " + x + "XXXXX| ");
            Write(" _____I_____\n| | | | " + x + s + "| |\n|_|_|_|_|_|_|");
        }
    }

    \$\begingroup\$ This is just some code not a function or program, you can compile it to a Func<int, string> which is usually the shortest way of doing it. \$\endgroup\$ – TheLethalCoder Oct 25 '16 at 12:47

    \$\begingroup\$ I bet you can save some bytes by moving the conditions to the Write instead of declaring and defining s. \$\endgroup\$ – Titus Oct 25 '16 at 14:06
