On Level 3 of the Palace Plateau, Cavendish is shocked to see Sugar's nutcrackers breaking apart on their own. Shortly, the nutcrackers turn back into people, with eight people being used to make each nutcracker.

Bartolomeo rejoices that he can make barriers again, Cavendish expresses anger that Sugar used her own servants to make the toys, and Gladius reflects with annoyance that Sugar was defeated once again. Meanwhile, Sugar's servants crowd around her, shocked to see her knocked out again.
