The excitement of the heist has now worn off following The Great Pet Heist, and Butterbean is bored. There's only so much adventure she can muster in the apartment, and she is itching for another good mystery to solve. When Mrs. Third Floor knocks on Mrs. Food and Madison's door in a panic, Butterbean and the other animals perk up. Is another mystery afoot? Mrs. Third Floor tells Mrs. Food and Madison she's experienced paranormal activity in the other apartment she owns on the 5th floor, and she doesn't know what to do. Mrs. Food, accompanied by Madison and all of the animals, head up to the 5th floor to investigate.

The animals discover that their friend rat Wallace has moved into that apartment, but though he's responsible for some of the food being eaten, he did not eat all of the fish in the aquarium, nor has he inflicted some of the damage to the apartment. It turns out that Mr. Wiggles, a famous octopus who performs tricks, has tired of the zoo life, and has escaped to this apartment thanks to a helping tentacle from his friend Chad, another octopus who lives in the building. Mr. Wiggles is the one haunting the apartment, and Butterbean and her friends are not necessarily pleased to find out he's living there.

When Mrs. Third Floor involves a duo of television ghost hunters who seem eager to rip her off, the animals must step forward to prevent her from being fleeced. Can they figure out how to remove their unwelcome guest and prevent Mrs. Third Floor from losing her savings to a bunch of crooks?
