The Countess's Calamity: The Box by Sally Gardner
When a box of toys is left, abandoned in the park, the toys really don't know what to make of it! Should they wait to be rescued and taken back to the 'land of lounge' or should they all scramble out and try to save themselves. Fortunately for them they are saved from making a decision with the intervention of two very nice mice. But the night is young, and their adventures are only about to begin. A touching book featuring the adventures and exploits of a mismatched group of friends who learn to live in harmony.
