I remember reading a webcomic back in the day and using the cute zombie as my Myspace avatar. (Yes, my back hurts. Why do you ask?) The comic had bright colors and was cute, not scary or sexy. The zombie character had brain sticking out of a hole on the top corner of his head. I didn’t remember any other characters or plot.
Searched around https://en.wikipedia.org/wiki/Category:2000s_webcomics for comics whose names sounded familiar and had no hits. Any ideas?
Yes! Thank you very much. How did you find it?
Dang, artist says they are reuploading the archive, but that site is broken. Oh well, at least I know now.
Your description was just right and jogged it from my memory petty much immediately. Glad I could help!
