In the chessboard scene one has to "freeze" Othello (the rat) to be able to start the game of chess.
Once Othello is frozen in place, enter the Storybook scene though the Telescope on the right and return to the chessboard.

Othello is still frozen, but now the door of the Piggy Bank is drawn in front of him.

There is more "broken" in this scene after returning to it.

1. The 'Chessboard' is not clickable anymore, rather it seems as if the game of chess has started. I'm able to move the pieces around. It seems that the Othello and door sprites are simply not removed or rather reset from the scene.
2. One can pick up Othello, but can't place him on the board anymore, since the game of chess seems to have already started. Once picked up and released again, he will babble something and go back to his hiding spot inside the piggy bank.

Looks like a script is not run (which would reset them), due to the scene change and the incorrect start of the chess game on returing to it. (But thats only me guessing.)

No idea if this is original engine's behaviour.
