Mini Boss:
The mid boss of the Nightmare version is a team consisting of Clefable, Espeon, and Dedenne, who are having a tea party. Clefable invites you over and tries to convince Espeon that you are Alice (as you are referred to as Alice the entire dungeon run. Choosing No when Clefable asks you if you are Alice will cause Clefable to say that you are clearly Alice). Espeon, however, has doubts. Then, Clefable's team challenges you to a fight. After winning, Espeon is finally convinced that the player is Alice, and Clefable mentions that the key she dropped was a Whimsical Key, which she has since she was a Cleffa. Then, Clefable and her friends return to the Tea Party, since they enjoy tea regardless if it is cold or not.
 * Clefable, Espeon, Dedenne (Dusk/Night)

Boss:
The boss is Malamar and Dragalde. Malamar tells the player (who is still referred to as Alice) that they are late, and tries to think up of a punishment. Dragalde mentions that "the little urchins" are missing. Malamar tells Dragalde that they are in the garden. She then tells the player that the pink things are disturbing the Nightmare kingdom, and the player is no exception. She then challenges the player to a battle, saying that she and Dragalde will purify the player. After the player wins, Malamar is shocked about her loss, and then, she realizes that the pink things are not bad after all. She then tells the player that she will let the pink things, and in extension, everyone in, regardless if they are good or bad. She then tells Dragalde that they have a party to attend to. The two then leave.
 * Malamar and Dragalde
