Poor Little Red Pen! She can't possibly correct a mountain of homework all by herself. Who will help her? "Not I!" says Stapler. "Not I!" says Eraser. "Yo no!" says Pushpin, AKA Senorita Chincheta. But when the Little Red Pen tumbles in exhaustion into the Pit of No Return (the bin!), her fellow school supplies must get themselves out of the desk drawer and work together to rescue her. Trouble is, their plan depends on Tank, the rotund class hamster, who's not inclined to co-operate. Will the Little Red Pen be lost forever?
