Yuuko gets the feeling that Mai is mad at her and tries to apologize in various ways, only to find out she was wearing headphones. Meanwhile, Nano and the Professor find a black cat and name it Sakamoto. The Professor makes a special scarf which allows Sakamoto to speak, although he ends up speaking in a rather condescending tone towards the two. Yuuko has an arm wrestling match with Mai, only to lose repeatedly to the latter. (Source: Wikipedia)
