OK, so not quite tabs, but sheet music!
You can also download the midi file to the music here. Very nice rendition of the track actually. Arranged by the incredibly talented Sebastian Wolff. You should go check out more of his stuff. Now. Go. Do it. I'll wait.
It's been pretty crazy seeing OMFGDOGS get as popular as it has. Thanks for the support everyone! Glad you like the lil pixel fellas. :)
