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

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 (022000@1)  A (x02220@1)Chorus:

D (xx0232@1)       Em (022000@1)       Bm (x24432@1)    F#mmix (244222@1)bag, grab bag, pop the question,

G (320003@1)           D (xx0232@1)               Ahave (x02220@1)a ball running wild between your spaghetti legs

D (xx0232@1)       Em (022000@1)       Bm (x24432@1) F#mmix (244222@1)bag, grab bag, dirty pots,

D (xx0232@1)         A (x02220@1)        Bmyou (x24432@1)best believe my love could fix the faucet

(Repeat Chorus)

Bm (x24432@1)              F#mBet (244222@1)you found something

A (x02220@1)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.
