Winter is coming, and Poppy and Sam's tiny garden neighbors are getting ready to hibernate. After stocking their pantries for the colder days ahead, Poppy and Sam settle in for a long winter's nap as well. But what is Poppy doing wrong? She can't sleep and nothing seems to work! Determined to hibernate like her friends, Poppy sets out with Sam to ask the other creatures for their deep-sleep secrets.

Translation of: Mimose et Sam, mission hibernation.
