Earlier this summer, Walker Books released two illustrated books in a new “Moshi Moshi Kawaii” series, in which you search for the bunny-pill characters, kind of like the Where’s Waldo? books. However, these characters aren’t new; they are originally from Japanese company Mindwave and were released in 2002 as “Usa Colle.” The company sold a limited selection of Usa Colle stationery goods and toys at the time, though they’re pretty hard to find these days.

The old site at UsaColle.com is a bit dated now and is mostly in Japanese, but it has some neat things to check out. There are images of all the original characters, short Flash animations to watch, pretty desktop wallpapers and printables to download, and even a cute little game to play.

See more of SquidPig’s cute illustrations on her deviantART account and the Squid & Pig blog. You can also shop for items featuring these designs at Squid & Pig’s Shop on Zazzle.

If you like what you see on the Sugar Bunny Shop, you can also see more of Celesse’s work on her gallery web site Bottled Talent, and she also sells some of her items on CafePress, Zazzle, and deviantART.

You can view some of the upcoming stationery items with Iiwaken on the San-X character page, and there’s also a printable calendar and desktop wallpaper on their goodies page.
