Ling Ling and Tong Tong are twin brothers. They occupy their territory at home everyday, using their neck to leave their scent on the furniture. The TV set belongs to Ling Ling and the top of the cabinet belongs to Tong Tong. The sofa is divided into left and right as well. Sometimes they fight. Luckily, they only nibble, jump and chase. When they are close, they will bathe one another and embrace one another to sleep together. They will develop new games such as biting plush dolls and magazines into pieces, producing a snowy scene inside the room. They also pull tissue paper from the toilet to fill the whole flat, letting us appreciate their artistic works for decoration. Recently, they have learnt to open the doors of the cabinet and rooms. All in all, new ideas and surprises everyday.
