Update: The Stick Figure Death Theatre has the 8th installment of the XiaoXiao series which happens to be part 2 of ? of the Mutilator (XiaoXiao No. 7 was part 1).

Other sites that host this phenomenon are:
- BetaBlue (www.betablue.com) ; was inspired by the XiaoXiao series and seeks to find the author (See his link to XiaoXiao)
- The infamous Stick Figure Death Theatre (www.sfdt.com) ; also has other varied stick figure animes - none as good as the XiaoXiao series IMHO.
