The Whole Cake Island is an island in the New World that is under the control of Big Mom, one of the Yonko, and appears to be her crew's base of operations.
The island owes its name to its resemblance to frosted cakes, and the buildings appear to be covered in what looks like icing. There are candle-like poles on the top the island that are lit on fire, making the island reminiscent of a birthday cake. The interiors of the buildings also look as if they are made of icing. The sky above the island is covered by unique purple and pink clouds.
