What things does Mij do which tell you that he is an intelligent, friendly and fun-loving animal who needs love?

Mij was an intelligent animal. It invented it own game out of the ping-pong balls. It screwed the tap till water began to flow and then it would play and splash in the water. Though it was aloof and indifferent in the beginning, it soon became very friendly. It formed a special attachment with Maxwell. It responded when Maxwell called out his name. It grew desperate when Maxwell left it in a box and it got hurt while trying to come out of it. After Maxwell took it out, it clung to his feet. It was a fun-loving animal. It enjoyed playing all kinds of games. It would play with a selection of toys, ping-pong balls, marbles, rubber fruit, and a terrapin shell. It required love and affection from Maxwell and it got that readily.
