One little chinchilla loves going to visit Auntie Iris — but there's danger in the air at the block of flats where Auntie Iris lives. . .There are bears on the first floor, crocodiles on the second floor, wolves on the third floor. Then one day, when Auntie Iris goes down to put out the rubbish she doesn't come back! Who ate Auntie Iris? Little Chinchilla bravely goes to find out. But who are the new neighbours on the fourth floor, and could they have something to do with Auntie Iris's disappearance?
