Found on Elephant 6 site, I just did some cleaning, added/fixed lyrics, and stuff.

(Original Tab by: Andrew Lillie (andrewzel@hotmail.com))

for this nice song, he's tuned just a (very) little bit sharp, but it'll still sound 
good if you're in regular tuning.

If you want to be a good monster, don't swallow mine
It's all fine and dandy, this slow betrayal
You found friends, to agree and understand
If you want to be a good monster, don't bother

Em    A

Chorus:

D         Em         Bm      F#m
mix bag, grab bag, pop the question,

      G             D                 A
have a ball running wild between your spaghetti legs

D         Em         Bm   F#m
mix bag, grab bag, dirty pots,

        D           A          Bm
you best believe my love could fix the faucet

D  Em  F#m  G  x3

You are a locked window, I can see in but can't get in
Locked in your room, until you've learned your lesson
I am a gift, which you refuse to open
If you want to be a good monster, don't bother

Em    A

Chorus:

D         Em         Bm      F#m
mix bag, grab bag, pop the question,

      G             D                 A
have a ball running wild between your spaghetti legs

D         Em         Bm   F#m
mix bag, grab bag, dirty pots,

        D           A          Bm
you best believe my love could fix the faucet

(Repeat Chorus)

D             Em
Chasing after honey
Bm                F#m
Bet you found something
D                 Em
Why name me what I want
Bm        F#m
If I am a gift
D                Em
Just waiting to be opened
Bm               Em
Coming out of my shell?
D         Bm
If I am a gift
F#m               Em
Why don"t you open me?

A


Haven't heard in this song in a long time, just trying to work it out from memory and 
the bit of tab I found.

Let me know about any mistakes you find, I am good at making them.
