But after a chance meeting with elegant Ruby Valentino, Queen of Valentine's Town, Sally begins having doubts about her newfound status as Pumpkin Queen. These doubts only grow upon their return to Halloween Town, as the residents begin pressuring Sally into fulfilling their ideas of a good queen. With Halloween only two weeks away and Jack focused on making the holiday a success, Sally despairs. Upset, she flees to the grove of portal trees, where she is drawn to one with a mysterious hidden door. Loyal ghost dog Zero stops her from passing through it, but on returning home, Sally discovers she may have let a terrible monster out of its prison. With the Sandman on the loose, the citizens of Halloween Town fall under his sleeping spell, and it's up to Sally to save the day.
