The most successful of RollCoCo's many works is the PiPi Panda set of Internet cartoon characters. The well known Taiwanese Internet portal Yam.com has even given the pandas their own web page, with a collection of animated greetings cards to download for free.
在精靈林林總總的作品中，以熊貓為造型的網路卡通角色「pipi 熊」最為成功，國內著名入口網站蕃薯藤還開闢了一個專門網頁，收錄 pipi 熊的各式動畫卡片，讓網友免費下載。
