yes Ameba Pigg is something like Habbo Hotel
if you have an Ameba account , you can do up your own design for your username & dress up in cool funky outfits & accessories
I've seen some artistes who use Ameba as the URL hosting site for their blogs & they also participate in Ameba Pigg
it's fun xD
This's SID's frontman Mao's Ameba Pigg design as an example on what I said earlier on
xD
