The episode opens with the The 7D with Lord Starchbottom running out of a haunted mansion with many buckets. Grumpy then recants the story of how they got there, why do they have all of those buckets, and what they're running from. Earlier, Queen Delightful summoned the dwarfs to obtain her buckets from her Uncle Humidor's mansion by the sea, which he no longer have use for it (she and her family had fled their home before, though she doesn't remember why) and it must be cleared out by the next day. Her buckets were very special to her, as she reminisce about playing with them on the beach while she was a child. The 7D then travels to the mansion with Starchy, leaving behind Bashful to protect Delightful.
By the time they arrive at the seashore, they meet Sally, who sells seashells along with other items that bear alliterative names. When they asked her about the mansion, she replies that it's haunted and she disappears. They entered the mansion, and they see a portrait of a girl. While they left Grumpy behind going to the next room, the girl suddenly comes out of the portrait and strums her guitar and sings "Where, oh where could my Mopsy be?", frightening Grumpy. When he tries to explain to Starchy what had happened, Starchy told him to concentrate and find the buckets.
The ghost girl continues to scare Grumpy while looking for her Mopsy. The 7D collects all of the buckets they could find and when they encounter the ghost, they flee out of the mansion in horror in the same scene that began the episode. Back at the castle, the dwarfs return the buckets, but the Queen is still somewhat sad. Suddenly, the ghost girl appears to face Delightful, and the two embrace. It's revealed that the "buckets" was actually the Queen's childhood "imaginary friend" and "Mopsy" is Delightful's nickname. Then, a family of ghosts appears (implied to have scared the Queen and her family out of the mansion years ago), frightening The 7D and Starchy out of the castle.
