Yume 2kki:Menu Themes

By using Urotsuki's computer, the player can choose between one of several different Menu Themes, which change the design of the menu frame. Menu themes can be selected through the tools menu on Urotsuki's Computer. There are currently 31 total in the game; at the start of the game, Urotsuki has 5 to choose from, and she can unlock more themes by interacting with special NPCs & objects throughout the dream world. These include the Eggs, special collectibles that first appeared in 0.100h, placed in specific areas of Wataru and shigurin's maps.

There are currently 26 unlockable menu themes in the game, 13 of which are egg themes, as well as a temporary menu theme, that once granted will not appear on the Menu Theme page.

Each Menu Theme is listed below in order according to the computer menu, along with a brief description of where they can be found.
