Meanwhile, the Big Mom Pirates Fleet has surrounded the Thousand Sunny as Smoothie and Daifuku begin their assault on the Straw Hats. Perospero notices that Big Mom has lost weight due to her chasing the Thousand Sunny for hours. Carrot tells the Straw Hats that she'll handle the situation due to the full moon and proceeds to transform into a Ceylon.
