Jack thinks that Oggy is a chess cheater because he won by checkmate, only because Joey took a pawn defending the king. Now Jack has divided the house using walls and distributed all things. Oggy has to stop this craziness because even the part in Oggy's wall-side is being robbed by Jack.
Once upon a time, a really bad time: Oggy and Jack were sleeping between a chess match. Joey shows up. He sees that they're asleep and takes distinct advantage and takes away a pawn. Joey rings a bell and he's out of here.... Ok, it's Oggy's turn. He sees that the pawn isn't there, defending the King, and he put his queen ahead the king, who had no way to run, and Oggy's Queen was supported by a bishop. Oggy only says that he defeated Jack for the first time. Jack looks angrily at the board and then at Oggy. However, Oggy maintains sportsmenship spirit and gives Jack a "Better Luck Next Time" hand-shake. Jack's snout turns bright red and he somehow slices off Oggy's palm to a pencil. Oggy got bewildered. Jack said there is no "Next Time" and walks off. Oggy rubbed the pencil to his head thoughtfully. Jack had now made walls and walls and all thing of the house were half-half, and Jack was completing a few bricks left for the wall. He threatened Oggy to never come to his side of the wall. Oggy shouted to apologize but Jack dropped a partiality parcel in his mouth. Oggy open his belly and took it out. He opened it and found a letter which had the writings on it in cursive : Cheater. Oggy looks up again but Jack drops a brick on him. Oggy walked away upset, saying why would anyone listen to me... Joey stood beside, chuckling in a frantic manner. He kissed the pawn saying he's the checkmate-guy. He walks away enjoying this rubbish war.
In the starting when Oggy was sleeping, his eyes were slightly opening.
