U-lu

A sheep from Hankagai, who describes himself as a Dog. This weird little sheep can sometimes change its form into a human and sometimes as a doggy (sheep). When he is in human mode, he can talk, drive, and even smoke. His attitude is like a 50-year-old uncle, a rude one. When in doggy mode, he behaves like a puppy and only barks. His wool is very defensive. It can withstand momentum impacts (forces). In the story, in order to restore the cube (the lost memories of a important person) in his body, he is needed to be taken to a place called "MegaSide" in Hankagai. (Source: Wikipedia)
