What's a fanlisting?
A fanlisting is just that: a huge listing of all the fans of a certain book, movie, band, etc. It's really not much more complicated than that.
What's Pucca?
Pucca was originally a digital animation called "Pucca Funny Love," originating in South Korea. The digital animation centered around a little ten year old girl, Pucca, her unrequited crush on the ninja, Garu, and her endless pursuit to get a kiss. The animation had little to no dialogue, and the tv series has followed suit by keeping Pucca and Garu's lines to little more than reaction noises.
The digital animation became popular all over the world, and inspired the TV series, produced by Studio B, currently airing on Jetix (Toon Disney) Monday and Friday nights.
